Well, that was entertaining and then some.
The Coolidge Corner Theatre showed a double-bill tonight (uh, last night): first, Raiders of the Lost Ark, which I haven't seen projected in, uh, well, 22 years... *sigh*... and second, Raiders of the Lost Ark: The Adaptation, which was hugely fun and which got a standing ovation from the audience (me included). The director of The Adaptation, Eric Zala, was there to answer questions, along with his younger brother, who played Goebler (and Colonel Musgrove, and "2nd Nazi", and, more disturbingly, the girl with "LOVE YOU" written on her eyelids). They obviously got a big kick out of seeing their film play for a crowd of enthusiastic, vocal Raiders fans, and Eric obligingly told us several anecdotes about the filming, including his horrible plaster-of-paris-gone-wrong experience.
Sadly, The Adaptation will probably never see a home-video release, because of the rights issues (even though it's hysterically funny, it wasn't trying to make fun of the original, so it isn't covered by the parody exemption). It's not available on the IntarWeb, as far as I can tell. And I've no idea when it'll get shown in these parts again. But if it ever does, go see it. And especially try to have just watched Raiders immediately beforehand: it improves the experience greatly.
