Not only has that not happened, I’ve not even heard that as a rumour (other than being included in various random tabloid wish lists, of which there is one per hour for the last 3 years at least).Anyhow, I thought Cavill was confirmed. I guess that's an internet rumor.
The only credible rumour was Aaron Taylor Johnson, which various outlets claimed had been been cast in the middle of last year, but that seems to have died off.
Right now it’s anybody’s guess.
