Although he's pretty handy behind a set of decks, it also appears that Kristian Nairn of 'Game Of Thrones' - best known for playing loveable giant Hodor - can also play thrash metal and was good enough to get through 'Holy Wars... The Punishment Due' with the help of Megadeth's Dave Mustaine.

The footage was captured behind the scenes, presumably at a Megadeth concert, and showed Nairn with Mustaine, bassist David Ellefson and drummer Dirk Verbeuren playing along with Nairn. There's probably a joke in there about Hodor and Holy Wars, but we're not seeing it.
