Kiefer Sutherland doesn't seem like such a bad guy!

While at this weekend's Comic-Con in San Diego, Freddie Prinze Jr. offered a controversial explanation as to why he hasn't been seen in the public eye for quite some time, putting the blame on Sutherland.

The two actors co-starred in the eight series of Fox's '24' back in 2010, in which Sutherland played the lead role of Counter Terrorist Unit (CTU) agent Jack Bauer, but for Freddie this experience nearly made quit acting altogether because of the Fox show's star being "unprofessional."

So what does the Golden-Globe actor think about this brutal diss?

"Kiefer worked with Freddie Prinze, Jr. more than five years ago, and this is the first he has heard of Freddie's grievances," Sutherland's rep told Fox News Monday afternoon (July 28th). "Kiefer enjoyed working with Freddie and wishes him the best."

That doesn't sound so unprofessional! Freddie blasted Sutherland in an interview when promoting his new Disney XD series 'Star Wars Rebels', and as the hateful rant continued, he said, "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. So, I just sort of stopped."

These issues Freddie suddenly brought up stem from Sutherland allegedly appearing on the set of '24' drunk and making all the crew wait hours for him, TMZ reports.

However, Fox officials have also adamantly denied these claims by stating that Kiefer was "nothing but professional during the run of the show and is beloved by cast and crew. It's so out of left field, 5 years later." An executive at the television network also noted, "We wouldn't have done another '24' if Kiefer were anything like Freddie described," referring to the recent miniseries '24: Live Another Day.'
