I met him! I stood right next to him and he's really Scottish, but I'm really Welsh lol. Yeah he was defo taller than me cos the top of my head just about reached his shoulder and I'm like 5 ft. ...so 5'10 ish.

Saw him once in a club, he's really slight built, Id say 5'9" at the most but prob closer to 5'8"

That Jane quote really surprised me when I first read it. For some reason, John comes across as more of a 5-9er in some of his roles.

Though he did look like a pretty good-sized fella in "Rebus," come to think of it.

From Jane magazine on filming Gwyneth Paltrow's Sliding Doors movie: "John, who is 5 foot 10, had to wear lifts during the close-ups, but took it as a compliment. "I was like, 'Wow, I've arrived,' because there woulda been a time in my career where they just woulda got a a taller actor," John brags. "They were worn by Tom Cruise, so I kept them."
