Robert Downey Jr. loves working with his wife.

The actor - who married producer Susan Levin in 2005, two years after they met on the set of 'Gothika' - admits he struggles more on movie sets if his spouse isn't there because they enjoy getting the chance to "escape" together.

He said: "We love working together. It's hard not to work together and, believe me, I know my place.

"Making movies is so energy and time-consuming that it takes you away from your real life for big chunks of time and, so, I get to escape with her as opposed to from her."

The 'Iron Man' star also claimed having a wife who works in the movie industry has helped him understand how much of a "creep" he can be.

He added: "Because I'm married to a producer, I'm also kind of being given an education into what it's like to manage a bunch of creeps like me, and what it actually takes to get something done."
