Damon joked in a discussion with The AP that Crowe's unique personality always seems to influence his actors.
"Everybody's playing him a little bit… There's a look that he gets," Damon recalled. "I see it a lot with Rene [Zellweger] and [Tom] Cruise in Jerry Maguire. I have it in this movie.
"It's that thing where somebody's explaining something to you and you're not quite sure what they're saying and you're trying to figure it out. It's this very Cameron kind of thing that's in all his movies."
Crowe also weighed in on We Bought A Zoo, saying that the film fits in thematically with his previous work such as Elizabethtown and Almost Famous.
"My dream was always to be able to be like a guy like Spike Lee or Woody Allen or [Francois] Truffaut where one day you can look at all the stuff and they all come together to give you a portrait of a human life, in different stages of it," the director commented.
"So I'm always looking for what's the next area of life to explore that will help me understand it and bring something universal to other people, too. I'll be doing that as long as I can, as long as there's a camera, or a page and a pen."
Damon recently revealed that he only starred in We Bought A Zoo because Crowe was the movie's director.
We Bought A Zoo is now playing in US cinemas and is released in the UK on March 16, 2012.
