Some people may recognize David Thewlis as Remus Lupin, the werewolf teacher, from the Harry Potter series of movies. His marriage to fellow actor Anna Friel lasted nine years, a lifetime in Hollywood. The couple seemed to be doing just fine and even starred in an upcoming movie together with Colin Firth and Keira Knightley. Despite how the marriage looks, it seems Friel is the one to blame for this break-up.

Anna Friel starred in a Broadway version of Breakfast at Tiffany’s. During the stage performances, she was seen snuggling up to co-star Jospeh Cross. Cross is 23 years old and 24 years younger than Friel’s husband David Thewlis. Friel said the two were just friends and continued with that story even though she was seen kissing Cross in December of 2009.

The rumor mill swirls in Hollywood, but when Cross moved into Friel’s home, things started getting a bit clearer; though the star did not admit to having an affair even when Cross moved in. She remained steadfast that nothing was going on stating that Cross was a friend and he could live there any time he liked.

Both Thewlis and Friel are accomplished actors so there should be very little to discuss in terms of a clean divorce.
