Jim Carrey has revealed he suffered for his new film, Mr Popper's Penguins.
Not only did the Ace Ventura star end up with smelly pockets, which he stuffed with fish for his feathered co-stars, he also had to endure icy cold temperatures on set.
"It was freezing on set all the time, just 30 degrees [Fahrenheit] - I was dying but the penguins were very happy. Then we'd go outside and do a scene on the roof where it was 80 degrees and I had to be in a Parka and five layers of clothing," he said.
"I literally almost fainted at one point. I was like, 'Get it off' and they had to tear the coat off me. And all they want is fish, so I carried fish around with me - in my pockets, shoes, everywhere. My life is very hard..." he added.
However, Jim - who plays a divorced businessman who inherits six Gentoo penguins - loved working with his furry friends in the big-screen adaptation of the 1938 children's book.
"Some people resist working with children and animals for fear of being upstaged," said the 49-year-old.
"But I love capturing the spark of innocence. And what's better than penguins, in our case, and children to bring that out in us? I liked working with them because it was always spontaneous; you never knew what was going to happen."
