Titanic and Aliens star Bill Paxton is joining the cast of Marvel's Agents of SHIELD for at least four episodes.

Paxton will play Agent John Garrett, an old colleague of Agent Phil Coulson's (Clark Gregg).

Garrett is not a desk jockey and will be in the thick of it with Melinda May (Ming-Na Wen) and Grant Ward (Brett Dalton).

Paxton will make his debut in the show on US screens in late February or early March.
