James Marsden: 'It's hard to act with CGI'

James Marsden has revealed that he found it difficult to work with the animated characters in his latest film Hop.

The actor spoke to Coming Soon about the movie, stating that the hardest part was trying to make it look like he was actually interacting with the animated characters.

"I can't stand these kind of movies where you see the characters and it doesn't look like they're interacting," Marsden said.

He continued: "I was always encouraging the animation artists and everybody to let me physically interact with him - putting him on my back and things like that - because I think there's a disconnect when you're working without an animated character who will eventually be there.

"That bothers me, when it doesn't work. Above the acting, that was the most important thing for me on this one."

Marsden is currently in talks to star in the thriller Loft.
