Has a tattoo that says "Mrs Fox 31.12.07" (the 31st of December being the date he married Billie Piper) on his left forearm. She has a matching one on hers.
While searching for what he really wanted to do in life, Laurence spent two years as a gardener before trying acting.
Noel Coward's song Don't Put your Daughter on the Stage Mrs. Worthington, was written for Laurence's great grandmother, Angela Worthington, who was a chorus girl at the time.
Laurence was born in Leeds, when his parents worked as missionaries there, and was brought up in Wimbledon.
Laurence was arrested for assault in April 2007, after attacking a photographer outside the theatre where he was appearing with Billie Piper. He received an official Police Caution. Due to strict Visa rules, this may prevent Laurence working in the US.
Fox went to the drama school RADA at the same time as the actress Katherine Heath.
Fox is in the 2007 film Becoming Jane alongside Anne Hathaway.
(on his family life growing up)
Laurence: We're quite emotional. We say what we think, but there aren't any deep, long-running grudges. There might be a blazing row and then 10 minutes later, it's forgotten. They'll stop you being a dick.
(on why he and his family often get cast in establishment/regal roles)
Laurence: Maybe we just look royal. We've got posh voices, but in the posh stakes we're at the bottom. My great-grandfather was a Jersey tobacconist and my great-grandmother was a showgirl.
(on Prince Charles, who he played in "Whatever Loves Means")
Laurence: I think he'll be a good king, actually. I think he's got a good role model in his mum. Maybe on occasion he says things that are not totally on the money, but I love the fact that he has a little village [Poundbury in Dorset], and I love the fact he doesn't like horrible buildings.
(on the contrast of his childhood at home to his days at boarding school)
Laurence: I was spoilt rotten - we all were. I was used to saying what I thought and there were no hierarchies apart from the family hierarchy. Then you get to boarding school and there is this mad, crappy system of pointless violence and intimidation.
(clarifying previous statements)
Laurence: I'd like to make clear, that I'm a Royalist in the sense that I'm not an Anti-Royalist, I mean, you could prune the Royal tree quite happily for me. I'm not overly thrilled about people getting loads of money, but they are quite busy. I mean, why shouldn't they take a plane somewhere? What's the queen supposed to do, get the tube? I think there's a lot of unfairness surrounding the Royal Family.
(speaking about his family)
Laurence: We are not a posh, rich family. We don't earn a huge amount of money. We are just a family. At no point do we have afternoon tea, although we have been to Harrow.
(on whether he had any preconceptions of appearing in "Lewis", the follow up to "Inspector Morse")
Laurence: I'd never watched any Inspector Morse before I took the role of Hathaway but now they've started repeated them during the afternoons I have seen a few and I really like them.
(on how his life is going)
Laurence: I had no expectations. I just want to work and be happy and do what I do. I don't want to be famous, but if being famous allows me to do the work that I want to do, then I'd do it.
