"He ambushes me to do projects with him, because he's literally about two minutes away. I'd have to barricade the street to avoid him, but then I'd get blackmail letters or something," Blunt, 29, jokes to New York magazine's Vulture. "He actually wrote the part in the movie with me in mind, or at least that's what he tells me. He probably told five other girls that!"
The movie, which comes out April 27, stars Blunt and Segel as a 20-something couple who keeps postponing their wedding for various academic and professional reasons. It's not the first time the two actors have worked together. They played love interests in Jack Black's 2010 comedy Gulliver's Travels.
"I have the most chemistry with people I genuinely love to hang out with. I find something that I love about them," says the actress, whose real-life husband is John Krasinski. "There's times you need to cultivate chemistry and invent it, and that's not as much fun. So it's great when you have a natural rapport, when you have natural warmth. That's why I do see the benefit of being open and easy-going and friendly on set, because that translates onscreen."
But Blunt says her chemistry with Segel is overshadowed by the scene-stealing performance of Alison Brie, who plays her sister in the movie.
"She asked me, 'Would you record your voice and tell me some stories?' so she could do an accent like mine," Blunt says. "And I told her all these stupid stories from my childhood, and now she sounds more English than I do!"
