While at Comic-Con over the weekend, Prinze blasted Sutherland and said working with him on the show 24 in 2010 made him want to quit acting. So what does Sutherland think of Prinze's major shade?
"Kiefer worked with Freddie Prinze, Jr. more than 5 years ago, and this is the first he has heard of Freddie's grievances," Sutherland's rep tells E! News in a statement. "Kiefer enjoyed working with Freddie and wishes him the best."

Among Prinze's choice words for Sutherland, he said the other day, "I did 24. 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."
The actor added, "I just wanted to quit the business after that. So, I just sort of stopped."
We're not sure what started the beef between Prinze and Sutherland, but perhaps it started after Sutherland's one-man attack on the Christmas tree community.
