There are two remaining Live and Onstage events at this year's San Francisco International Film Festival.

On Sunday, photographer Mary Ellen Mark will deliver this year's State of Cinema Address, in which she will take the audience on a private tour of her film-set images, discussing the legendary figures in the frame as well as what was going on around them, and how what she experienced has informed her photographic and film work. She will also show and discuss her photo-essay Twins and screen its companion short film, made with her husband, Martin Bell, and discuss photography and cinema with the audience. SF Appeal is currently doing a giveaway for this event!

1 p.m. (Sunday, May 3) // Kabuki (1881 Post St) // $10-12.50

Next Tuesday, at The Lost World with Dengue Fever, Cambodian pop band Dengue Fever will provide a live soundtrack to the silent film The Lost World, a prehistoric adventure flick based on Sir Arthur Conan Doyle's book of the same name. The film, which was a smash hit upon its release in the mid-Roaring Twenties, features stop-motion sequences by animation pioneer Willis O’Brien, who later animated King Kong, accompanied by outlandish costumes and sets. This annual event tends to be hugely popular, so buy tickets in advance, and line up early!

8 p.m. (Tuesday, May 5) // Castro Theatre (429 Castro St) // $15-20
