In the next year, Alan Alda will play both a villain and a hippie. The 74-year-old actor has signed on to appear in two comedies for Universal Pictures: First, he will play Carvin, the head of a naturist village in Wanderlust, a film starring Jennifer Aniston and Paul Rudd as a married couple trying to escape their modern society. Then he will take on the role of a Bernie Madoff-type baddie, playing a Wall Street capitalist who has defrauded his employees of their pensions in the action comedy Tower Heist, which Brett Ratner is directing. Filming on Tower Heist is scheduled to begin next month.
