Samuel L Jackson will make a reappearance as Nick Fury in the upcoming season finale of Marvel's Agents of SHIELD.

The Avengers Assemble star, who previously featured in the ABC TV series in a pre-credits tag, revealed in an interview with Vulture that he recently filmed another cameo.

Asked if he was returning to Marvel's Agents of SHIELD, Jackson replied: “I did! Last week! I just shot the end-of-the-season show.”

But Jackson was much more tight-lipped over the exact details of his appearance, saying: "You're trying to get me fired and killed! I don't talk about Marvel's business.

“None of us do . . . If they ask [Marvel Studios boss] Kevin Feige and Kevin says, 'We'd like for you to do it', I do.”

Marvel's Agents of SHIELD continues on Sundays on RTÉ Two.
