For comedy-action-drama, try "RED," with Bruce Willis, Morgan Freeman, John Malkovich, and Helen Mirren. The Harry Potter movies are pretty good for all three of those elements; though, the last few are a bit darker, with more violence and less humor. "Thor" and "Iron Man" are pretty good, too. The first "Beverly Hills Cop," with Eddie Murphy is very good as well.
