A comedy show to benefit the Southampton Lions Club and the North Sea Fire Department will take place Saturday at 8 p.m. at 230 Elm Street in Southampton. Laughs will be provided by Lynne Koplitz, a veteran of stand-up who has appeared on “The View,” Comedy Central, the Food Network, and elsewhere, and Pete Correale, whose many credits include “Let Me Tell Ya,” a one-hour Showtime special. Tickets are $30, and a 50-50 raffle will be part of the festivities.

Exactly one week before Halloween, two artists decided to offer their own trick and treats at a small beachfront cottage in Bridgehampton destined to face the wrecking ball. 

On Oct. 24, the artists, both East End residents who wish to remain anonymous, mounted a temporary show of textile and ceramic works at 77 Dune Road. According to an email sent by someone representing the artists, the pieces were made in tribute to the memories they had of growing up in the community during the 1970s and similar cottages that have vanished over the years, replaced by much larger houses.

In place of a long-gone door screen, a sampler of sorts was stitched to a piece of sheer white fabric. It said, “This house has survived 23 hurricanes, 14 nor’easters, two super storms, 22 blizzards. But it will not survive their plans to demolish it. Save this house and keep its gentle footprint.”

A colorful knitted scarf or runner seemed to replicate a series of windowpanes where ospreys, whales, and other indigenous creatures were represented in drawings that were attached to the knitted material. Ceramic vases and trays were embellished with shells.

The theme of the work was “the inherent beauty of a small footprint created in tandem with the natural landscape.” The artists said such Dune Road beach cottages were once plentiful and “were cherished getaways for working middle-class families, as well as the wealthy.” The occupants maintained them with care and minimal decoration. Their attention was focused on the beauty of the “outer environment rather than the house itself.”

According to the property listing, the house was built in 1956 and is 1,200 square feet with two bedrooms. Zoning allows the half-acre lot to accommodate  a building of 2,700 square feet, but an architect has already devised plans for a 4,000-square-foot house with a pool and deck. Variances would be needed to realize them.

The artists said the house was maintained until the mid-1990s but has had virtually no occupants since then. The price tag is $8.9 million.

In addition, they said, the dunes in front of the house are home to many indigenous species of plants and wildlife that used to characterize Dune Road, including beach rose, various beach grasses, bayberry, pitch pine, and goldenrod. “On a recent morning, monarch butterflies were seen flying in and out of the dunes,” the email said.

On the day of the guerrilla installation, 40 invited guests viewed the show and then enjoyed a party on the beach near the house.

“We realize what we did was not particularly legal, but it was important to us to honor this beautiful house and spotlight the unsound trend of tearing down these shingle beach houses to build gigantic ones in their place,” the artists said.

Although the show was temporary, they did leave two of the pieces at the house. “We hope that our message will be heard, by realtors and potential buyers, that this house, and the land it sits on, is worth saving.”

National Theatre Live will return to Guild Hall with an encore screening of “The Deep Blue Sea,” a masterful drama by the English playwright Terence Rattigan, on Saturday evening at 8. 

Set in West London in 1952, the play centers on Hester Collyer, who is discovered by her neighbors following a failed suicide attempt, after which the details of her affair with a former R.A.F. pilot and the breakdown of her marriage begin to emerge. Directed by Carrie Cracknell, the production stars Helen McCrory as Hester, which is considered one of the greatest female roles in contemporary drama. Tickets are $18, $16 for members.

Guild Hall’s artXchange, a free celebration of cultural diversity, will take place Sunday from 1 to 4 p.m. The family afternoon will include workshops led by visual and performing artists, a multilingual poetry reading, dance and music performances, and other activities aimed at fostering respect and interaction among the East End’s communities.

Work by two of the Watermill Center’s resident artists will be presented on Saturday when Andrew Ondrejcak opens his studio between 2 and 3 p.m. and Ebe Oke holds an open rehearsal from 3 to 4. 

Known for large-scale environmental installations, Mr. Ondrejcak is a production designer whose works have been presented in New York City at the Kitchen, BAM, and the Public Theater, among others, and at venues in Europe. While at the center, he is working with his collaborator, Shara Nova, on a new opera inspired by Virginia Woolf’s “Orlando.”

Mr. Oke is an experimental artist, electroacoustic composer, and performance poet who creates avant-garde pop music exploring the idea of otherness. His compositions often incorporate the sounds of birds and insects, reflecting a childhood spent on an exotic bird farm. He has studied with Karlheinz Stockhausen, collaborated with Brian Eno, and performed widely. Both programs are free, but advance reservations are required.

Photographs by Jacob Fellander, a Swedish artist whose large-scale cityscapes and landscapes have been prominently displayed at c/o the Maidstone inn in East Hampton, will be featured in the new film “Inconceivable,” a psychological drama written and directed by Jonathan Baker and starring Nicolas Cage, Faye Dunaway, and Gina Gershon. The film began production on Oct. 10 and is scheduled for a 2017 release.

Had enough of the 2016 presidential campaign? A visit to Bay Street Theater in Sag Harbor on Saturday evening at 8 will transport you back to the 1960s for an evening of music. “The Sixties Show” features seven New York rockers who will perform music by the Beatles, the Byrds, the Beach Boys, the Kinks, Buffalo Springfield, the Who, Bob Dylan, the Doors, Cream, Moody Blues, and other iconic acts of the period. 

The band wears the mod clothing of the ‘60s and plays live with instruments and amplification from that era. Archival and newsreel footage from the ’60s will be projected on a large screen behind the performers. Tickets to an evening of time travel are $30 in advance, $40 on Saturday.

On Saturday afternoon, the Watermill Center will present the latest open-rehearsal performance of its resident artist group Bruno Guida and P.L.U.T.O., an ensemble of stage directors, actors, and writers formed in 2015 at Lincoln Center’s Directors Lab. The performance, “Black Box,” examines the group’s various backgrounds and cultures. 

According to the center, “In advance of their residency, each member has been assigned to bring one black box with the precise measurements: 30 cm x 30 cm x 30 cm. The contents of the box will contain elements related to their personal history and their country’s identity, including a piece of news from a paper or magazine, a book, a song in MP3 format, and two surprise elements, among other objects.”

The performance begins at 2 p.m. and will be preceded by a 1 to 2 p.m. tour of the center. Reservations are required for both events and can be made through the website. 

Prudence Wright Holmes, an actress with extensive credits in theater, film, and television, will bring her solo show “Agatha Christa Is Missing!” to the Montauk Library on Sunday afternoon at 3:30.

Ms. Holmes portrays the ace detective Clarissa Marbles in what she calls “an interactive murder mystery” generated by the strange disappearance of the doyenne of British crime fiction. Gunshots, screams, and laughter keep audiences on their toes.

Her credits include the Broadway show “Happy End” with Meryl Streep, the original production of “Godspell,” the films “Sister Act I and II” with Whoopi Goldberg, “Kingpin” with Woody Harrelson, and more than 100 television commercials.

The Parrish Art Museum’s Salon Series of classical music concerts will conclude its fall run with a performance by the Bulgarian-born pianist Nadejda Vlaeva tomorrow at 6 p.m. Among her many awards are first prize in the Liszt Competition in Lucca, Italy, and the Yahama Award for best Brahms interpretation.

The program reflects Ms. Vlaeva’s eastern European roots, with works by the Ukrainian composer Sergei Bortkie­wicz, the Russian-American composer Vladimir Drozdoff, and the Polish-born Franz Liszt. She recently premiered works by Bortkiewicz and Drozdoff at Carnegie Hall and received critical acclaim for her CD of Bortkiewicz’s piano music.

Tickets are $20, $10 for members. A reception will follow the concert.

The Southampton Arts Center is taking Halloween seriously this year. In addition to its Spooktacular Haunted House and its exhibition “Chas Adams: Family and Friends,” both continuing through Monday, the center will screen two creepy classics this weekend.

“Poltergeist,” Tobe Hooper’s horror fantasy about an ordinary California family’s frightening introduction to the supernatural, will be shown tomorrow at 8 p.m. Tickets are $8.

On Saturday at 10 p.m., the center will present its “first annual screening” of the cult classic “The Rocky Horror Picture Show,” the 1975 film that not only combined three genres — musical, comedy, and horror — but also spawned the phenomenon of audience members dressing as the characters and performing along with the film. To encourage that, the center will have props available for purchase and will award a prize for best costume. Tickets are $10.
