Tom Hanks has revealed his favourite trait in co-star Julia Roberts - the high standards she expects from her friends.
The actor, who wrote, produced, directed and stars alongside Julia in the film Larry Crowne, said she had a high "integrity bar".
"I like about her that she suffers no fools," he revealed.
"She's got an integrity bar that if you pass, you should feel good about yourself."
Larry Crowne marks the two Hollywood stars' second collaboration, after they appeared together in 2007's Charlie Wilson's War.
The film tells the story of a middle-aged Navy veteran who goes back to college after losing his job.
"Long ago I was at junior college with people like Larry Crowne," Tom revealed.
He added: "I always thought that would be an interesting theme on which to build a movie."
