^ it's not that there's no love for that idea, it's just that its not very likely. It's probably a quarter of a century since he last did UK TV. I think his last US TV appearance was in Friends, which always attracted big stars.
I think for the most part, people are thinking about who is likely to appear as well as who they'd like to see. Of course Oldman would be a great Master - probably a great Doctor too - but I'd say there's virtually no chance of him doing it.
