"Legends" Trailer #1 : "You were never supposed to remember," an unnamed voice exclaims. "Remember what?" asks Sean Bean. "Who you are." No, the above quotes aren't from "The Bourne Television Series." They're from the trailer for TNT's new action drama, "Legends," starring "Game of Thrones" & "Patriot Games" star Sean Bean. Based on the novel by Robert Littell, "Legends" follows Martin Odum, an FBI agent deep undercover who can change his identity at the drop of a hat. All that cap switching gets to his head, though, when someone starts asking the right questions, and Odum begins to doubt who he really is. To increase the prestige factor, "Legends" has at least three "Homeland" veterans behind it. Howard Gordon ("Homeland"), Alexander Carry ("Homeland"), and Jonathan Levin ("Charmed") make up an impressive group of executive producers and the pilot was directed by David Semel, who directed episodes of "Homeland," "American Horror Story," and "Hannibal." If TNT is going to finally break the mold from too-tame network fare ("Falling Skies" included), this is the show to use.
