Prinze did a stint on the fan favorite "24", and had a few words to say about the experience.
"I did 24, and it was terrible. I hated every moment of it. Kiefer was the most unprofessional dude in the world. That's not me talking trash. I'd say it to his face. I think everyone that's worked with him has said that."
He went on to say, "I went and worked for Vince McMahon at the WWE for Christ's sake, and it was a crazier job than working with Kiefer. But at least he was cool and tall. I didn't have to take my shoes off to do scenes with him, which they made me do. Just put the guy on an apple box or don't hire me next time. You know I'm six feet and he's five four."
Prinze, who dished while at San Diego Comic Con, was there to promote his new Disney XD series "Star Wars Rebels".
