Washington West Film Festival
The Washington West Film Festival isn’t just about the movies — it’s about effecting change, as all box office proceeds go to benefit charitable organizations. This year the money goes to: the Arcadia Center for Sustainable Food and Agriculture, which raises awareness about healthy food, food access and sustainability; Kids in the Spotlight Inc., which trains underserved youths to create, write, cast and star in their own short films (two of which will screen at the festival, presented by “Modern Family’s” Ty Burrell); and the Robert Duvall Children’s Fund, which supports charities looking out for poor, distressed or underprivileged families. This year’s lineup is packed with 56 films; the spotlight screening is “Clive Davis: The Soundtrack of Our Lives,” a documentary about the music producer who, since the ’60s, has shaped what we hear on the radio. A Q&A with the filmmakers and Davis follows the screening (Bow Tie Cinemas Reston Town Center 11, 11940 Market St., Reston, Va.; Fri., 7-11 p.m., $35).
Various locations; through Mon., free-$35 per film, $70-$180 for packages and bundles.

“The Cabinet of Dr. Caligari”
You can’t see “The Cabinet of Dr. Caligari” exactly the way audiences did in 1920. But you can at least see it — and with added bonuses. At a screening of the gothic classic of silent cinema Sunday, you’ll also get the little-known 1917 short “The Devil’s Assistant” and Andrew Earle Simpson on piano. Simpson, the resident film accompanist at the National Gallery of Art, creates music that goes with silent films. For “Cabinet,” which is about a hypnotist who uses a sleepwalker to commit murder, we anticipate a lot of creepy gloom, unless Simpson accidentally brings sheet music he wrote for Charlie Chaplin’s “City Lights,” which would be pretty funny.
Atlas Performing Arts Center, 1333 H St. NE; Sun., 4 p.m., $20.

“Little Shop of Horrors”
It’s just a typical story of boy meets plant from another planet, plant from another planet turns out to be evil, plant from another planet commits murder. But it’s a musical! Frank Oz’s 1986 version of “Little Shop of Horrors” is getting special screenings for Halloween; you can hear classic songs like “Somewhere That’s Green,” “Feed Me (Git It)” and the scariest one of all, Steve Martin’s paean to mouth pain, “Dentist!” It’s the exclamation point that makes it really scary.
Various locations; Sun. & Tue., 2 and 7 p.m., various prices, go to fathomevents.com for details and participating theaters.
