The Man of Steel star has been rumoured as a candidate to play BDSM enthusiast Christian Grey, with Ian Somerhalder and Ryan Gosling also apparently in the running.
During a recent interview with Details, Cavill was asked if he would like playing a character as dark as Grey.
"Whether that happens, that decision will be made at the time it has to be made," Cavill answered.
The actor then joked: "It would be a very different kind of thing than Man of Steel."
Fifty Shades of Grey was recently slated by Kristen Stewart, who compared the literary series to pornography.
"It's just so raunchy! I mean, obviously, everyone knows that," she declared recently. "But when I see people reading it on planes and stuff, I'm genuinely creeped out.
"Like, you're basically just reading porn right now! Get that blanket off your lap!"
