'House' to move from Fox to NBC?

Reports have suggested that House may not air on Fox in the future.

According to Variety, the network and the show's production company NBC Universal are struggling to come to a deal for an eighth season.

NBC Universal is now thought to be planning to offer the show to other broadcasters if an agreement cannot be made by April 15.

One of the possible new homes for House is thought to be NBC itself. However, House's executive producer David Shore told reporters that he is not worried about the show's future.

"I would be absolutely astounded if there wasn't [an eighth season]," he said. "Fox wants to have a season eight, and NBC Universal wants them to have a season eight. I fully expect there to be a season eight and we're proceeding on that basis."

Robert Sean Leonard has admitted that he is uncertain if he will return to House next season. None of the medical drama's lead cast - except series star Hugh Laurie - are currently contracted for an eighth year, with Leonard recently signing up to star in Broadway play Born Yesterday.

"This is my last season of House," he told TV Line. "I'm shooting my last episode now. Contractually this is it. There's also no deal for House [as a series] next year because Comcast bought NBC Universal and no-one has a deal."

He continued: "If I do House next year it'll be under a new umbrella. But legally and contractually, I'm free after this [season]." However, Leonard then added that he is uncertain if he will remain with the show or not. "The long and short of it is, I don't know," he said. "I assume they'll make another year of House. And I assume I will do it. But I can't say for sure."

The actor went on to say that if House is renewed, he will have to miss "quite a few" episodes due to his Broadway commitments. "I would either have to not be in the first few episodes or they'd have to delay the start date," he claimed. "Or I can be written lightly in them and shoot a couple of Mondays here and there. Anything's possible."

He also denied that the show's upcoming seventh season finale will write out his character James Wilson. "That's not the plot of the episode," he insisted. "That's not what the episode is about at all. [Wilson] can't just go away. The show just isn't structured that way. He has to be there. It's the way the show works."
