EXCLUSIVE: Amber Valletta is set to co-star opposite Sean Bean in TNT’s drama pilot Legends, executive produced by Homeland‘s Howard Gordon. Also cast in the pilot, based on the novel by Robert Littell, are Rob Mayes, Tina Majorino and Lux Haney Jardine. Legends centers on Martin Odum (Bean), a deep-cover CIA operative who has an uncanny ability to transform himself into a different person for each job. Valletta will play Martin’s ex-wife and mother to preteen Aiden (Jardine), who thinks Aiden got his smart mouth from Martin. Mayes will play Troy, a former Special Ops guy with a “mission-first mentality” who now works as a federal agent with the DCO. Majorino will play Maggie, the newest member of the DCO field support team.

Valletta, who recurred on the first season of ABC’s Revenge, is repped by CAA, 3 Arts, and PJ Shapiro. Mayes, repped by The Collective and UTA, recurs on Lifetime’s The Client List and plays the title role in the feature John Dies At The End, which opens next month. Majorino has been recurring on Grey’s Anatomy and True Blood. Gordon, Jeffrey Nachmanoff and Mark Bomback developed Legends, which is produced by Fox 21.
