"The Adventures of Pete & Pete," Nickelodeon
Playing a perpetually cast-wearing weirdo on "Pete & Pete" was a surprisingly good platform for Trachtenberg, who parlayed her Nick series into a Nick movie ("Harriet the Spy") a starring role on "Buffy" and a moderately successful film career. After a stint as villainous Georgina Sparks on "Gossip Girl," she'll appear in NatGeo's original movie "Killing Kennedy," as Marina Oswald, the wife of JFK's killer.
Status: Still soaring
