Bill Paxton

Former Big Love polygamist Bill Paxton — who showed off his action chops in movies like Twister — will begin an arc of at least four episodes on ABC's Marvel's Agents of S.H.I.E.L.D. starting in late February or early March. "We wanted to bring in a rough-and-tumble former cohort of Agent Coulson [Clark Gregg] with a little bit of attitude and cigar-smoking swagger," says executive producer Jed Whedon

Paxton plays Agent John Garrett, who will work alongside agents Ward (Brett Dalton) and May (Ming-Na Wen) and "comes into the fold in a very surprising way," says executive producer Maurissa Tancharoen. "He is the type who wants to stay out in the field no matter how high-level he gets."

In the comic Elektra: Assassin, S.H.I.E.L.D. turned Garrett into a cyborg to save his life after he was injured in the line of duty — but all Whedon will say is that "when Garrett got his promotion to Level 7, he refused to sit behind a desk and doesn't like the formalities of S.H.I.E.L.D. He's going to help Coulson solve some mysteries and is not afraid to rig an explosive or two."
