Freddie Prinze Jr. dubs Kiefer Sutherland an ‘unprofessional dude’

Freddie Prinze Jr. really didn’t think his “24� co-star Kiefer Sutherland was all that.

Prinze, the former staple of high school movies, spoke up about Sutherland while promoting his latest show, “Star Wars Rebels,� at Comic-Con in San Diego over the weekend. He actually bashed the Fox star, whom he appeared alongside in 2010, according to ABC News’ Jason Nathanson.

“I did ’24.’ It was terrible. I hated every moment of it,� the 38-year-old said, apparently unsolicited. “Kiefer was the most unprofessional dude in the world. That’s not me talking trash. I’d say it to his face. I think everybody that’s worked with him has said that.

“And I just wanted to quit the business after that. So, I just sort of stopped.�

Sutherland’s response Monday came in the form of a statement from his rep.

“Kiefer worked with Freddie Prinze Jr. more than five years ago, and this is the first he has heard of Freddie’s grievances,� publicist Annet Wolf said via email. “Kiefer enjoyed working with Freddie and wishes him the best.�

Prinze hasn’t had the most prolific career in recent years; since “24,� the “Robot Chicken� voice star has done only a few guest appearances, on shows including “Bones� and “Witches of East End.�

The actor, who is married to “Buffy the Vampire Slayer� alum Sarah Michelle Gellar, elaborated, saying that he went on to work for WWE promoter and chief executive Vince McMahon and even though “it was a crazier job,� it was better than working with Sutherland, 47.

Prinze’s first work with WWE actually appears to have been in 2008, and according to IMDb he also played himself in a 2010 episode of “WWF Raw,� now known as “Monday Night Raw.�

“At least [McMahon] was cool and tall,� Prinze said. “I didn’t have to take my shoes off to do scenes with him, which [‘24’] made me do. Just put the guy on an apple box or don’t hire me next time. You know I’m 6 feet and he’s 5[-foot-]4. What do you want me to do?�

Sutherland is actually more like 5-foot-9, officially -- though apparently that still wasn’t quite enough.
