Mark Wahlberg's kids have landed their first film roles in dad's new Transformers movie.
All four of the actor's kids with his wife Rhea Durham will appear in Transformers: Age of Extinction - the fourth installment in the robot wars franchise.
Wahlberg tells MTV News, "My kids just did a cameo, just scared people in the street looking up, but they did a great job.
"I was so nervous because (director) Michael (Bay) doesn't have time for bad performances. You have to understand; you're shooting a $300 million movie... You've got a lot going on. He's got five, six takes. If you ain't (sic) got it, you're done. I didn't want to see my kids get clipped. They were excited about it, but they started to get mad at me because I'm trying to over-direct them. It went great."
The film will hit cinemas next summer (14).
