Count everyone, from Garner to Victor Garber, who played Sydney's enigmatic father and fellow agent Jack Bristow, pleasantly shocked to have secured a role on Alias. "I was convinced that the guy who went in ahead of me was going to get the part, because he looked exactly like I thought that Jack Bristow should look," Garber recalled to TV Line. "I said, 'Why am I here? This guy is perfect…' I was stunned to get it, frankly. Very happy."

Michael Vartan, who played Vaughn (or did he…?), said that both he and Bradley Cooper, who was cast as Sydney's conflicted (and not just because of the frosted tips) journalist pal Will Tippin, thought they'd blown their audition. In fact, Vartan did flub his first read ("I was sweating profusely"), but a second try went better. "It's funny, because after we read, Bradley and I were just hanging out outside," the actor recalled. "We looked at each other and we were like, 'Dude, we're not both getting this part."…Lo and behold, we both got the job."

Surprisingly, Vartan didn't have to do a screen test with Garner first, but, he added, "I challenge a paper bag to not have chemistry with Jennifer Garner." (So, let's just say, she'd never been kissed by Vartan until the script called for it.)
