Anything with Cary Grant.
Philadelphia Story -- a chick flick that guys can like.
cary grant is just awesome. but he was also an actor in a time where many movies weren't all that outlandish. perhaps romanticized, but possible- and many were based on true stories. and the vast majority of movies appealed to everyone.
admittedly, i like watching jet li action movies for the impossible yet neat fight scenes, but my all time favourite action movies will always be captain blood (errol flynn) and the mark of zorro (tyrone powers).
