Dr. Strangelove is a pretty awesome movie, although I haven’t seen it since my film class at community college over a year ago. (Never take film studies at a community college, by the way.)
Anyway, the final line in Dr. Strangelove where Peter Sellers gets up out of his wheelchair was apparently improvised after he forgot that he was supposed not supposed to be able to walk. I mean, I guess the line is silly and funny and it totally works, but how the hell do you forget that your character is in a wheelchair?!
