Charlie Day has confessed doing voice work is easier because he doesn't have to worry about his looks.
The 37-year-old Horrible Bosses actor voices the role of Art in Pixar sequel Monsters University, and joked that while his looks might be fading, his voice is still keeping him in work.
Charlie quipped: "Let me tell you it's a relief - because my face is a mess, and getting worse year by year, by year, by year. So it's nice to just walk in and speak into a microphone, because the voice is a mess too, but apparently people like it. So I brought my mess to the studio and then they sift out anything good and draw a little monster and I take a nap and then watch a movie.
He added: "All I had to do was voice the lines, it's really quite an easy job for me! It's a real treat."
The Pacific Rim star is already signed up to voice a character in The Lego Movie, but he is also in talks to team back up with Jason Bateman, Jason Sudeikis, Jennifer Aniston, Kevin Spacey and Jamie Foxx on Horrible Bosses 2.
He said: "It's going to mean make-up and hair... I'm excited for that too, because as much as I enjoyed being a little purple monster, I also still enjoy being myself. I still like acting.
"I can't wait. The joy of the first movie was the people, so if we can do it again and work together again, I'd love to do it."
