Movie/film suggestions.

@immatthewj No, I am not ashamed to love Steve Martin either. (aside from Father of the Bride stuff)

I love a lot of comedies. John Cusack too.

@grislybutter ...Midnight Run is a classic. Might have been DeNiro’s first comedic role and he surprised the crap out of me he was so good at it. Another great DeNiro romantic comedy was Mad Dog and Glory with Bill Murray and Uma Thurman.

Trading Places is an all timer too....Terrific cast with Ackroyd, Murphy, Curtis, Don Ameche and Ralph Bellamy. I also loved Jamie Lee in A Fish Called Wanda with Michael Palin, John Cleese and a wacky Kevin Kline.

Also a John Cusack fan. His best role may have been in the underrated Grosse Point Blank where he played a hitman.

I mentioned The Quick and the Dead earlier, another top notch Western was Silverado. A few other good modern Westerns: 3:10 to Yuma, Hell or High Water, Hateful Eight.

Steve Martin in Roxanne! And don’t get me started on The Princess Bride.

If you like classic comedies but have seen the "usual suspects," my wife and I really enjoyed "The Devil and Miss Jones" with Jean Arthur and Charles Coburn.  I thought I'd seen them all but not this one.  As far as that goes, *any* Jean Arthur movie is worth watching. ;-)

If you have a hankering for vintage musicals, don't miss "Romance on the High Seas."  I know, I know--Doris Day?!?  It was her first movie, extremely well directed by Michal Curitz, who discovered Day and could direct just about anything, including "Casablanca" and "Yankee Doodle Dandy."  Day is charming and sings like an angel, and Oscar Levant delivers some terrific one-liners.  It's quite fun.

Going back to Albert Brooks in Lost in America, I love the scene at the casino where Albert tries to talk the casino boss into giving back the "nest egg" his wife had lost. Classic.

@ezwind I am not a huge fan of Gross Point Blank, charming but the script a bit lazy, relying too much on the stars. 

@immatthewj The Favor is a delightful comedy with Brad Pitt.
