Pretty Woman director Garry Marshall is known for his broad, successful comedies, that take a wholly unlikely look at life. But they're never meant to be more than amusing, forgettable fodder, and that sounds just like what his next film will be. The director has attracted a barrage of talent to Valentine's Day, an ensemble piece that has just added That 70's Show star Topher Grace to a cast that already includes Anne Hathaway, Jessica Biel, Bradley Cooper, Ashton Kutcher, Jessica Alba, Jennifer Garner, Shirley MacLaine and Emma and Julia Roberts. Grace will play Hathaway's boyfriend, while Roberts will play a teenager looking to pop her cherry with her boyfriend.
