Captain America" star Chris Evans and actress Anna Faris hit the red carpet earlier this week in Los Angeles for the premiere of their latest collaboration, "What's Your Number?" Based on Karyn Bosnak's book 20 Times a Lady, the film is typical sweet romantic comedy. 　　"What's Your Number?" stars Faris as Ally Darling, a young woman, who decides to reevaluate the twenty men she has dated in the past, after reading a magazine article warning that people who have had 20 or more relationships have missed their chance at finding true love. She sought help from her neighbor, Colin Shea, played by Chris Evans, to join her on her quest.When speaking of her latest flick, Faris said that she had a great time shooting the film. "We're really excited, it's an R-rated comedy and it's raunchy, fun and funny. So, it's exciting for me and just the type of comedy that I want to do." Evans, who is riding high following the summer blockbuster hit "Captain America," joked about his fellow cast members at the premiere. "I hated everybody and it was a miserable experience. No, it was fantastic, everyone got along phenomenally well, really well. I know every movie says that but we got along really well." "What's Your Number? is scheduled to open on September 30th both in the U.S. and Taiwan.
