Olivia Munn, Jennifer Lawrence, Patton Oswald and Michael Fassbender (among others) took part in a table reading of "The Big Lebowski" this weekend. I found this article about it, with a video clip attached.

It's not the whole reading, but I'm not sure if there's a video of that. I'll look around to see if there is one. Found several easily googled articles about it, however.
That's cool, thanks !
