You have to be careful with magic dust. You never know what kind of trouble it's going to get you in. Take Jenna. One minute it's her 13th birthday, the next, thanks to a quick sprinkle of something enchanted, she's a 30-year-old babe with a glam job and live-in boyfriend. It's kind of like Big for girls, sweet and funny with a great central performance from Jennifer Garner, the square-jawed sexpot from action show Alias and upcoming superhero flick Elektra. Who knew she was so funny, though? Lord of the Rings fans have the added thrill of seeing Andy Serkis in action, not as computer generated marvel Gollum, but, believe it or not, as an actual person!
