Mark Wahlberg fractured his knuckle shooting new action movie 'Max Payne'.
The actor - who stars as the title character who attempts to avenge the murder of his wife and daughter in the film - was left with the painful injury after shooting some of the more physically exhausting scenes in the movie.
He said: "I fractured my knuckle shooting this action movie, 'Max Payne', and I keep re-injuring it! It's usually when a nice older lady wants to say 'Hi' and then shows you how strong she is and just mashes your thumb.
"And playing the Nintendo Wii video games console causes me lots of pain, but I still play it with my daughter. The tennis really killed me - I'd never seen my daughter so happy though! You'd have thought that I'd bought her pony or something! Luckily it doesn't bother me playing golf though!"
Mark - who shot to fame as baseball-cap wearing singer Marky Mark in 1991 - also revealed he will find it difficult to explain his embarrassing past to his three children, four-year-old Ella, two-year-old Michael and one-month-old Brendan Joseph.
He said: "When I was Marky Mark, I thought I was the coolest guy in the world but really I was just a jacka**!
It's a tough one I've got to explain to my daughter one day! And no, I don't fancy going back to music. I feel a lot older and a little wiser. I learn something every day from meeting people, my kids, my job.
This career path has afforded me a great education out of school. If it all ended tomorrow, I'm pretty damn happy." The DVD of Mark's latest movie 'The Happening' is released in the UK on November 3.
