USA Today brings us the following:
...Cavill just signed on to star as a spy in Guy Ritchie's adaptation of The Man From U.N.C.L.E., replacing Tom Cruise, who is no longer associated with the project. He is tight-lipped about his Napoleon Solo role except to say he'll be alongside The Lone Ranger star Armie Hammer, who will play Illya Kuryakin.
"Things are full-steam ahead. It's all very early days. But it's gonna happen," Cavill says before pausing. "Well, this is Hollywood. It's supposed to happen."Cavill's current film, "Man Of Steel", opens on 14 June.
