I'm very sorry if this is old news, but as far as I can tell this film festival was still fairly recent. The question was asked regarding the third film and Mr. Ramis seems less than enthused. He really sounds more like Murray on the matter. The GB3 discussion starts at 1:30.

the recent films he was talking about were, made in 06-07 ( Walk Hard, Knocked Up). so this is before the Office writers were donned to write the new film. but still a good listen to hear some of his thoughts on writing and directing.
