( CNN ) -- Freddie Prinze Jr. and Kiefer Sutherland have very different memories of working together on `` 24 .

'' Prinze did n't leave acting -- he was at San Diego Comic-Con over the weekend promoting his Disney XD series `` Star Wars Rebels , '' and has worked on TV series `` Bones '' and `` Witches of East End '' within the past year . But according to Prinze , it was Sutherland in particular who made him want to throw in the towel . `` Kiefer was the most unprofessional dude in the world , '' Prinze said of the `` 24 '' star . `` That 's not me talking trash , I 'd say it to his face . I think everyone that 's worked with him has said that . '' Well , it does n't seem that way . In a statement to ABC News , Sutherland 's rep said that Sutherland did n't know Prinze was n't his biggest fan . `` 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 said . `` Kiefer enjoyed working with Freddie and wishes him the best . ''
