The Public Enemies star - who has 10-year-old daughter Lily-Rose and Jack, seven, with French singer Vanessa Paradis - is worried his children’s interest in his career will see them follow in his Hollywood footsteps.
He said: One thing is certain - neither of them will ever get bored. I always show them my various costumes and they love it. My children seem to take my job for granted. But I honestly hope that Lily-Rose and Jack don’t want to become actors that’s my greatest fear!
Johnny says his family is the most important thing in his life and he is more interested in pleasing them than winning acting awards.
The 46-year-old star explained to Germany’s Joy magazine: I'm just an actor and not a hero. It doesn’t make any sense to me that I should leave the world anything. To me only one thing is really important - I want my children to be proud of me!
