Kate Hudson is known as the likeable star in romantic comedies like " How to Lose a Guy in 10 Days" and "You, Me and Dupree."
Some may wonder why Hudson chose to play Darcy, the slightly abrasive best friend of Ginnifer Goodwin's Rachel, who is getting married to Rachel's law school crush.
"It was different," Hudson said of the role to media outlets at the film's premiere on Tuesday, May 3. "She's definitely not the likable character. So, for me, it was really fun to play. It lent itself to some really good comedy when you're playing someone who only cares about themselves."
She adds, "For me comedically, and where this would go if we get to do the sequel, is what I found really interesting about Darcy."
The film is based on a book of the same name by Emily Giffin which was released in 2005. The novel has a sequel called "Something Blue," which focuses on Darcy.
The movie about a wedding also coincidentally had a ripple effect on the actor's personal lives. Star Ginnifer Goodwin announced her engagement to actor Joey Kern in December 2010. Hudson, meanwhile, recently announced her engagement to boyfriend Matthew Bellamy.
John Krasinski also admitted he and actress Emily Blunt wed shortly after he finished filming the movie. "We made a pact and we said that if we're not all married by the end of the year after the movie then we're all in trouble," the actor joked.
The film also hits theaters on May 6, a week after the royal wedding.
"I think the wedding hype that has been going on has been really fun," Krasinski said at the film's premiere. "It just reminds everybody that as much as weddings can be a nightmare, there's still something about you that always wants them to be really fun and work out."
Krasinski also says the movie's portrayal of weddings and relationships are a little more true to life than most romantic comedies.
"In this movie I think the relationships are dealt with a lot more in a real way. Not to say that this movie is exactly how real life happens but, it's a little dirtier," he said. "It's not like the main characters get together right away. You know, people are making hard choices and hard sacrifices. There's cheating involved, that's never fun but it's kind of more real."
"I feel like this is a really relatable romcom," Goodwin added. "If we can even call it a romcom. I've been calling it a 'rom with laughs.'"
