Jackson Rathbone (Finding Carter) has joined the Season 4 cast of The Last Ship, TNT’s drama that already has been renewed for a fifth season. Created by Hank Steinberg and Steven Kane based on William Brinkley’s popular novel, The Last Ship chronicles the aftermath of a global catastrophe that nearly decimates the world’s population. Captain Tom Chandler (Eric Dane) and his crew must confront the reality of their new existence in a world where they may be among the few remaining survivors. Rathbone will recur as Giorgio, a rich, Greek-American playboy who is charming but also is a dangerous thug. He uses his considerable wealth and power to make the Mediterranean his playground. Rathbone played vampire Jasper Hale in the Twilight movies and recurred on MTV’s Finding Carter. Other credits include the upcoming features Until We Meet Again and Justice. He is repped by Innovative Artists, Link Entertainment and attorney Peter Nelson.

Darren Mann (Ice) has booked a recurring role in TNT’s vampire drama pilot Let the Right One In. The eerie drama follows Henry (Benjamin Wadsworth), a young boy who long has been tormented by his classmates and finds solace in a friendship with a charismatic female vampire (Kristine Froseth) who appears to be near his age. The vampire settles into the boy’s small town with her mysterious caretaker, just as a series of bizarre murders begins attracting the attention of law enforcement. Mann will play Lukas, the alpha male of a cluster of teenage bullies. He has made Henry his personal whipping boy and delights in tormenting him to the brink of unconsciousness. Mann’s credits include Windfall, Hello Destroyer and the upcoming DirecTV series Ice. He is repped by APA and Webster Talent Management
