Matinees on the Mountain

On select Saturday afternoons in the summer, the historic Mount Wilson Observatory screens a decades-spanning lineup of sci-fi and astronomy-inspired shorts and feature-length films. Unlike the San Gabriel Mountains site’s concert series and stargazing sessions, Matinees on the Mountain doesn’t take place inside the dome of the 100-inch telescope. Instead, screenings take place inside the 256-seat auditorium inside the astronomical museum, the same venue used for the site’s Talks & Telescopes lectures.
