This is the highest quality I've seen so far, but it's not the scene. The scene where he shows off his ass happens during the first 5 minutes of the movie. I don't know why BBC made this movie so hard to watch and find in decent quality.
That's where I got the gif from, it's the only link to the full movie I've found, sadly it's very low quality. There has to be a HQ rip somewhere.This is all I could find, though I'll keep looking. If there's a scene in a better quality than the video below, there has to be the full HD version as well
From all the information I've gathered and interviews I've seen he has not mentioned a girlfriend, wife, or if he's dating anybody. The most I've been able to find of him on his dating life is a picture on his Instagram with a woman but the picture is captioned "We are friends not lovers. Thought it was funny cos it that kind of pic hahaha" and then in the comments he clarifies that he is just friends with the woman in the picture.Has anyone heard of him ever having a girlfriend or wife? I haven't.
And just to keep the thread going
I totally think he's gay, or at least bi. I haven't been able to find any proof, but I haven't been able to find proof that says otherwise either. From the interviews I've seen of him he just gives of a vibe and I wouldn't be surprised if he is.
