13 Going On 30
Fans of the TV series Alias will know that part of what makes Jennifer Garner's Sydney Bristow such an excellent secret agent is her ability to commit herself fully to her undercover identities, developing a different personality for each new role. Fans will also recognize that Garner's own remarkable acting skills are what make the character work: Not only does she nail each undercover identity, but she also lets Bristow's personality shine through all the put-on personas. Though the film gives her ass-stomping abilities a rest, those Alias skills make Garner uniquely suited to star in 13 Going On 30, in which she plays a 13-year-old who magically wakes up in the body of her 30-year-old self, as if she'd skipped the years between 1987 and 2004. She's convincing as a teenager in a grown-up body, but she's also convincing as a teenager in a grown-up body trying her best to act unfazed by the adult world.
