Honestly? He's such an ingrate that at this point i'd be VERY disappointed if someone would PAY him to be involved... Perhaps someday, if he gains a new perspective and embraces his fellow cast & crew, and the fans- but why hope to see a Guy who's basically dissed the Whole Whoniverse?
I'm afraid this is ridiculously inaccurate. He's done absolutely no such thing.
He has said, as is quoted above; "I was open-minded but I decided after my experience on the first series that I didn't want to do any more," he said.
"I didn't enjoy the environment and the culture that we, the cast and crew, had to work in," he continues. "I thought if I stay in this job, I'm going to have to blind myself to certain things that I thought were wrong."
He had problems with behind-the-scenes politics.
