They're set to play an immortal alien race in Marvel's upcoming blockbuster, The Eternals.

And Kit Harington, 33, and Richard Madden were hard at work as they filmed for the action-packed movie in Camden, London, on Wednesday.

The Game Of Thrones stars reunited for the shoot with Bodyguard actor Richard, 33, seen suspended in the air over a bridge during one intense stunt scene.
