Chris Pratt gets to voice all the characters, apparently.
According to HollywoodReporter:
Chris Pratt is going to voice the lasagna-loving, Monday-hating comic strip feline Garfield in a new animated movie.
Andrew Kosove and Broderick Johnson’s Alcon Entertainment is behind the new Garfield, which has been picked up for worldwide (excluding China) release by Sony Pictures. The script, written by Oscar nominee David Reynolds (Finding Nemo), is being directed by Mark Dindal (Chicken Little), with the duo having previously worked together on Disney’s The Emperor’s New Groove.
Created by Jim Davis, Garfield first appeared in comics sections in 1978, with the lazy, orange tabby cat often causing problems for Jon Arbuckle, his human owner, and the lovable household dog Odie. Garfield, which debuted in 41 newspapers, currently holds the record as the most widely syndicated comic strip in the world.
