A new Ice Age movie is in the works. The movie will be the sixth installment in the core computer-animated franchise about a group of prehistoric animals who unexpectedly come together during the Ice Age. John Leguizamo, who lent his voice to Sid, a ground sloth, revealed the news in an interview with NPR. "We're about to do Ice Age six," he said, while discussing his career highlights. While he did not provide any additional information about the upcoming film, the movie could potentially reunite the main cast of the 2002 film, which also includes Ray Romano as Manny, Denis Leary as Diego, and director Chris Wedge as Scrat. Leguizamo went on to talk about how he created Sid's voice for the original movie. "I did, like, 50 voices for the director, Chris Wedge, and he wouldn't - he said, they're - I just want you to do your voice," the actor explained. "'I go… I don't want to do my voice. I want to do a voice. I'm an actor.' So I did a Southern voice for the sloth 'cause he's slow. Then I went a little more ghetto one. And he goes, 'Nah.' Then I got Discovery Channel footage, and I saw that sloths stored food in their cheek pouches, and they - it would ferment, and they'd get drunk."
