I did the same, Top Gun and Top Secret, then Willow, Real Genius, and The Saint, et cetera. Went back to Colorado for a bit, mentioned watching some of his movies to a friend, ended up watching At First Sight, because she wanted a chickflick. Not a great film, and I swear there was an actual Mira Sorvino nude scene in it, but it was just obscured. I was probably thinking about that deleted scene of Marisa Tomei in Wild At Heart, most likely.
Any way, I do that for all of my favorite Actors, I'll watch a few I really like, then a few of the either lesser known ones, or the ones people say sucked, to watch it from a different perspective.
I really like the Val Kilmer Cameo at the end of the Psych series, it's funny because Shawn and Gus were huge Kilmer fans.
