For a woman who spends the majority of her time either wielding three-pronged daggers or blowing away members of the Covenant, Jennifer Garner is pretty damn perky. Why, I'd even go so far as to say she has all the charm and charisma of a giddy 13-year-old! Which works out swell for a movie called 13 Going on 30. Yes, it's just a female version of ''Big,'' and yes, the story is fairly disposable, but gosh if Garner doesn't somehow pull it off.
Whether she's squirming during a striptease or persuading a clubful of hipsters to reenact Michael Jackson's ''Thriller'' dance sequence, Garner does dorky to a tee. Maybe it's because she's had some practice: Somewhere in between the plentiful but uneven crop of deleted scenes and the video for Rick Springfield's ''Jessie's Girl'' lies the bonus feature ''I Was a Teenage Geek!'' in which the star talks about being a band nerd in high school, with photos backing up her claim...irrefutably. (She's lived it, people!)
