Segel says, "I was told that it had to be conceivable that Emily Blunt would ever choose me to be her husband... They (producers) sent a trainer to the set and I had to work out twice a day and then he would watch me eat all day."

But the actor found a way to cheat during the shoot - so he could nibble between takes: "I play a chef in the movie and so there are a lot of scenes where I had to eat. I was paying my co-stars phenomenal amounts of money to mess up their lines during the scenes, so I would get to keep eating."
