Bruce Willis is "unbearable" to work with when his family do not accompany him on his travels .
The 'RED 2' actor insists his wife Emma Heming and their 15-month-old daughter, Mabel Ray, join him when he is on location, because he just can't bear to be away from his girls.
He told FemaleFirst: "I'm fortunate that I get to bring my family with me when I travel. It would be impossibly unbearable for anyone I'm working with if I didn't have my family with me. I'd just be moaning about that. I have a little baby and I like to hang out with her every day."
Doting father and husband Willis - who also has three daughters, Rumer, 24, Scout, 22, and 19-year-old Tallulah, with ex-wife Demi Moore - isn't sure what makes his marriage to Emma work, but feels it's important to pay attention to your spouse.
Bruce added: "Attention must be paid to your family and your friends and how you treat them. I don't think there's anything more important than that."
The action movie legend - who is known for his hard-man character John McClane in the 'Die Hard' films - also reveals that he no longer does his own stunts for fear of being "scolded" by his wife.
He added: "I do let the stuntmen take over. I don't do that many stunts. I would do the stunts if I could but I'm not allowed to ever, ever - they hurt. I wouldn't mind being hurt. I mean, I get hurt all the time, but I'll get scolded [if I do them]."
'RED 2' is in cinemas on August 2.
