We have Alias to thank for introducing us to Jennifer Garner. She played the super sexy— and deadly—CIA agent, Sydney Bristow, a Krav Maga expert who's fluent in 30 languages (31 if you count the language of love). It may be hard to keep track of the double agents, the triple agents, backstabbers, and secret government agencies, but Alias will never be called boring or predictable. We're talking explosions, knife fights, guns, and a bountiful selection of wigs! Did you really expect anything less from creator J.J. Abrams?
