The 44-year-old actor, who is married to Rachel Weisz, said that filming his scenes as Bond in the upcoming film "Skyfall" was all-encompassing and he struggled to switch off when he headed home, reported Daily Express online.
"When I am doing the movie, I am totally single-minded. It is to the detriment of my personal life," Craig said.
However, the actor also said that he is thankful that his family understands him very well.
"Fortunately I have a very understanding family and they understand that that is part of it and that it is all-encompassing. I keep my energy levels as high as I can all the time," he added.
