Hollywood heart-throb Colin Farrell passes time on movie sets by singing songs from famous musicals. Farrell is currently filming ASK THE DUSK with Salma Hayek and Idina Menzel and loves the attention he gets when he serenades his beautiful female co-stars. Menzel gushes, "He would sing RENT songs to me. He told me how much he loved musical theatre, which you would never know."
