height?

i really love this actor but i was always curious as to how tall he is because im thinking 6'4 his wife the beautiful keeley hawes is actually 5'10 ( and they have her listed as 5'8" and she said in an interview she's 5'10) and he still taller than her when she's in heels and when he was in P&P he almost hit the guy that plays collins in the face and that actors like 5'4 5'5 and keira is actually only 5'7 because he towered over her and keira said that he was a big guy and not what you usually see on film. I also heard alot of actors have to lie about there height like lee pace who is actually 6''6 and they have him listed as 6'3". just curious if anyone knows :)
