"All I can tell you is if Ron Perlman is free, he will be in," del Toro told us. "I wrote a part for him. He read it and if everything falls in place, Ron Perlman has a role in it written specifically for him."
"Ron plays Larson, the sort of dog guy, the guy that cares for the dogs and the sled - the part of the expedition that is dog sleds," he explained. "It's a fantastic character. I really love him. He's sort of a pragmatic guy, doesn't care about science or the mythology or the cosmology. He just is a hard-boiled Nordic man, and it is written specifically for him."
Guillermo del Toro is currently in pre-production on the film.
No production date has been set.
