In Tower Heist, he'll co-star with Ben Stiller for a comedic role. The film tells the story of a team of maintenance workers at a Manhattan high-rise building who use their knowledge of the building to organize a heist from the penthouse tenant, a Wall Street capitalist -- who Alda plays.
So, these two projects should be nothing short of hilarious. Alda has proved time after time that he's a very funny, comedic actor (his guest spot on 30 Rock as Alec Baldwin's loving, touchy-feely (and liberal) father, anyone?). Although I'm sure that both films won't be anything mind-blowing or spectacular, they still (especially with his presence) will be fun.
