Michael Keaton has been in "White Noise" and "Cars" in recent years, and is in "Toy Story 3" this year and no doubt the follow up to "Cars" too.
With all the "Ghostbusters 3" stories going about, I remember reading something about Rick Moranis retiring after his wife dies in the 90s.
Don't know if you're being sarcastic, but he's currently in "Prince of Persia" and was in "Shutter Island" with Leo DiCaprio this year. Also heard something about a possible kindofsequel to "Sexy Beast".
