David Boreanaz At Comic-Con: 'Bones' Actor Mocks 'Castle' Star Nathan Fillion


David Boreanaz wasn't afraid to say exactly what he thought of "Castle" star Nathan Fillion during the "Bones" San Diego Comic-Con panel on Friday.

After seeing that "Castle" was featured on the back of a TV Guide issue that had "Bones" on the front, Boreanaz began mocking Fillion for halting production because of a contract dispute.

"I want to work four days, not five," Boreanaz joked.

In less tense "Bones" news, creator Hart Hanson promised Comic-Con goers that Season 9 would see Booth (Boreanaz) and Brennan (Emily Deschanel) tie the knot.

“We’re not fooling you — they will get married this season,” Hanson said, according to TVLine.

"Bones" and "Castle" will return to Fox and ABC in the fall.
