Paul Rudd has signed on to play opposite Michelle Pfeiffer in the upcoming Amy Heckerling comedy "I Could Never Be Your Woman," says The Hollywood Reporter.

Also on board are Stacey Dash, Fred Willard, Tracey Ullman, and newcomer Saoirse Ronan.

"The Heckerling-penned movie follows a mother (Pfeiffer) who falls for a younger man (Rudd) while her daughter (Ronan) falls in love for the first time. Ullman plays Mother Nature, who meddles in their fates."

Paul Rudd and Stacey Dash worked with Ms. Heckerling on the hit "Clueless." The veteran director was also behind the camera for comedies like "Fast Times at Ridgemont High," "Johnny Dangerously," "European Vacation," "Loser," "A Night at the Roxbury," and the first two "Look Who's Talking" movies.

Mr. Rudd, for his part, is also set to score a lot of laughs in next weekend's "The 40 Year-Old Virgin."
