Tim Allen has complained the hit animated movie character Buzz Lightyear is tough to voice because he has so many personality changes.
Disney Pixar's Toy Story 3 sees Buzz reset to his original factory settings so he forgets his toy friends, and he even ends up in Spanish mode.
Tim moaned: "I have a lot of personality disorders in this one; I get reset, I'm a different guy, another guy comes up. I always get to play this complicated Buzz that has different personality disorders."
Co-star Tom Hanks, who voices cowboy Woody added: "He speaks Spanish in this. Didn't they try to get you to record in Spanish for a little bit? That's what I heard. It was the 'buzz' around the studio."
Tim admitted: "It didn't go so well."
But he added he loves being Buzz, despite his crazy traits, as he is such fun to play.
Tim said he enjoys the role: "Because he's a spaceman. Because he's deluded and he gets to scream and yell."
::Toy Story 3 is out on DVD and Blu-ray now.
