A new film written and directed by a local filmmaker will screen at the Sebastiani Theatre at 12:30 p.m. on Sunday, Aug. 5.

The film, “Remember Isobel,” is a benefit for Alzheimer’s disease research and tells the story of a woman losing her mother to Alzheimer’s and the effects of that loss on her marriage to her wife, her relationship with her kids and the extended family.

Sonoma native Sarah Barbulesco-Lamb will present the film along with a number of the actors and production staff who will be available for a short question-and-answer session following the screening of the film.

The film stars Don Most, Bonnie Hellman and Ronnie Marmo.

Tickets for adults are $15 and seniors are $12.
