Channing Tatum was too ''intense'' for his wife to be around when he was filming 'Foxcatcher'.

The 34-year-old actor had gotten so deeply into the character of wrestler Mark Schultz when Jenna Dewan-Tatum - with whom he has 17-month-old daughter Everly - visited him in Pennsylvania that she cut her trip much shorter than planned.

Jenna, 33, admitted: ''I was pregnant, so I came already hormonal.

''It was so interesting because he was so in character, channelling this sort of intense dark character that I was like - and it was winter - I'm going to go back to California!''

Channing admitted it was hard to shake off his alter ego at the end of a day's filming with director Bennett Miller.

He said: ''Bennett creates an environment that you can't shake off at the end of the day. And, you know, you try to come home and make her laugh, [but ] I just couldn't do it. I tried.''

However, the 'Magic Mike' actor also admitted he felt his wife's pregnancy made her more sensitive to the situation than she otherwise would have been.

He laughed:''And pregnant women - if you don't know - are very emotional as it is.''
