This is Rory McCann who played Sandor Clegane aka The Hound in Game of Thrones. He was backpacking with Arya Stark before biting it (courtesy Brienne of Tarth) in season 4.
Deepika Padukone, who has been shooting for xXx: The Return of Xander Cage in Toronto met McCann recently. They met because he is also in the movie. Here is a photo of them goofing around between takes.
And for us losers who will never get any opportunities to hang with The Hound, here is a GIF-t.
