Steve Carell is back and this time he is not a virgin. He’s a nutty gay uncle. “Little Miss Sunshine” is a comedy road trip that stars Greg Kinnear and Toni Collette as a married couple who drive from Albuquerque to Redondo Beach so that their daughter, Olive (Abigail Breslin), can compete in a kiddie beauty pageant. Along for the ride – don’t ask why – are Olive’s heroin addicted grandfather, (Adam Arkin), Nietzsche-worshiping brother, (Paul Dano), and gay, suicidal uncle, (Steve Carell). This is not “National Lampoon’s Vacation.” It’s a vacation for a whole new generation.
