The 61-year-old actor and musician recently auditioned for the role of a slave who leads a rebellion "like Spartacus", and if successful will join his son Alfie Allen on the HBO fantasy drama, reported Daily Express.
"Every scene is a bloodbath. Frankly I think I'm cut out for that," Allen said.
Meanwhile, Allen also revealed that he had previously auditioned to play the on-screen father of Alfie's character Theon Greyjoy.
However, he claimed that he deliberately "did a rubbish audition" because he found the offer "a bit cheesy" and "a bit obvious".
