Rachel McAdams was in awe of Lindsay Lohan

She told Allure magazine: "If anything, I was in awe of her talent.

"I looked at her as this experienced actor, and she had great comedic timing, so natural. It's just funny to hear that because you never know what people are thinking. We all try to act like we've got it together."

Meanwhile, Rachel - who also stars as Ryan Gosling's love-interest Allie Hamilton in the drama 'The Notebook, and in the psychological thriller 'Red Eye' - is hoping that taking on a variety of roles will help her to achieve a "complicated" career.

She explained: "I'm hoping it's going to be complicated and have lots of dead ends and corners and sharp turns. I hope it can't be summed up too easily when I'm done."

'The Notebook's' director, Nick Cassavetes, recently opened up about the difficulties surrounding Ryan, 33 and Rachel's relationship, as they struggled to get along on set.

The 'Crazy Stupid Love' star even asked Nick to find someone else to play his on-screen partner during filming because of his lack of chemistry with her.

However, rather than giving up on the pair - who later dated on-and-off for four years - Nick decided to set up an impromptu therapy session.

He told VH1: "We went into a room with a producer, they started screaming and yelling at each other. I walked out ... I smoked a cigarette and everybody came out like, 'All right let's do this'. And it got better after that, you know? They had it out.

"I think Ryan respected her for standing up for her character and Rachel was happy to get that out in the open."
