Los Angeles, Sep 5 :  Actor Daniel Craig feels he is so engrossed in his work that he cannot pay much attention to his personal life.

"When I'm doing the movie, I'm totally single-minded. It is to the detriment of my personal life," Empire magazine quoted him as saying.

However, the 44-year-old, who is married to actress Rachel Weisz, is thankful that his family understands him very well.

"Fortunately I have a very understanding family and they understand that that's part of it and that it's all-encompassing. I keep my energy levels as high as I can all the time," he said.
