Benedict Cumberbatch's name has been linked with the role of Martian Manhunter in The Justice League, but will he be making an "evil" appearance in the Batman vs Superman: Dawn of Justice movie?
Well, we're not too sure about this one just yet.
We asked him on the red carpet of the GQ Men of the Year awards, but Benedict wouldn't spill.
"That's a fun one, I've not heard that one until tonight," he said.
Benedict was presented with the best actor award by his friend Dan Stevens.
But when we asked Benedict whether he was down to play Mr Martian, he said: "I'm going to let that rumour run."
We also asked how he felt about statisitcs which said he was more popular than Jay Z and Beyonce after tickets for an upcoming theatre production of Hamlet, which he's due to appear in, sold out faster than the couples' On The Run tour.
"Well, I'm a bit embarrassed about that," he said.
"But at the same time, the fact that Hamlet has sold as fast as the king and queen of popular music for their tour is just so thrilling."
He added that the popularity for tickets wasn't putting pressure on him.
"It's wonderful. It means people want to come and see it.
"I mean, it would be far more pressure if we were going, 'Christ, how are we going to sell this on top of having to actually come up with the goods?'.
"I'm really excited about it and we're going to give it a great, great, great version."
