One of the biggest challenges of working with a bunch of penguins is – well, you might call it cold feet.

The new movie Mr. Popper’s Penguins, starring Jim Carrey and Carla Gugino, features the work of eight live penguins (in addition to some CGI penguins), and to accommodate the subarctic creatures, the film set had to be kept between 45 and 50 degrees Fahrenheit – at all times.

“Basically, the set was so cold that I was fighting pneumonia the entire time,” Carrey said at a press conference for the film. “I don’t even think it’s really about the health of the penguins. It’s cause they’re method [actors]. That’s what I found out.”

“It was sort of selfish on their part,” Gugino remarked.
