Actor Blair Underwood is so hooked on showbusiness, he spends family vacations shooting home movies with his kids.

The Dirty Sexy Money star steps behind the camera to direct his wife Desiree, sons Paris, 11, and Blake, seven, and nine-year-old daughter Brielle, as they travel around the globe.

He reveals to OK! magazine, "We shoot movies 'on location'. The kids write and star in them, and I direct them. We do posters and soundtracks too."

And he admits the process has given Brielle the acting bug: "The boys couldn't care less, but my daughter is into it. We were shooting a scene in Rome, and she said to me, 'Can I get an agent and do this for real?' Oh man."
