Wannabe warblers Gwyneth Paltrow, Huey Lewis, Paul Giamatti, Maria Bello and Andre Braugher hit the karaoke circuit for prize money and a chance to feel like "a star for three minutes." The feel-good romp shines when the stars are on-stage crooning (all except Braugher do their own singing). Lewis and Paltrow's duet on Smokey Robinson's "Cruisin'" is a standout.
