Blunt: My own wedding was a breeze!

Emily Blunt has revealed her own wedding preparations couldn't have been more different to those of her character in The Five-Year Engagement.

The actress plays a bride-to-be with a long and bumpy build-up to her big day in the new comedy, which also stars Jason Segel. But Emily's own nuptials to US actor John Krasinski were much less stressful.

"I didn't want to have a big wedding. I wanted to keep it really laid-back," the star said of the intimate ceremony at Lake Como, Italy in 2010.

"I'm quite decisive. I'm not one of those people who says, 'Oh, what about this, what about that?' I'm just like, 'That'll do, that'll do, that'll do', because I just think it's the day that's special, not all of the stuff that comes with it.

"The day should be kind of freewheeling a little, because something could go wrong. You've just got to roll with the punches."

Emily, who plays academic Violet in the comedy, said the film depicts a more realistic relationship than most movies.

"We didn't really want to do that Hollywood gloss of the romantic comedy that we're used to seeing," she said.

"We wanted to make it really real and accessible and naturalistic, kind of messy."

:: The Five-Year Engagement is released in cinemas on Friday, June 22.
