Jennifer Aniston loved working with "extremely dedicated" Aaron Eckhart.
The pair played a troubled couple in 'Love Happens' and the actress admits she couldn't imagine starring in the movie with anyone else.
She said: "Aaron is spot on and moves you so much. I found him extremely dedicated and focussed. When you work with a performer like that, you constantly have someone giving you something good to volley with.
"He's really gorgeous, he really is and so funny, wickedly funny and he's very interesting. He's deep, Aaron's deep - he's a thinker - so we just had a ball together.
"We laughed, I love his sense of humour, I love him talking about philosophy and psychology, he's great."
The 'He's Just Not That Into You' star was particularly attracted to the movie because it was so different to any other romantic comedies she had seen.
She added: "It's not your typical love story. It's about two people who are starting a scary, new beginning. Eloise sees an opportunity to fix something, and Burke is looking to be healed. For him, it's the first time he's allowed his heart to feel.
"When you do that, you have to clean out the skeletons, whether you want to or not."
