Henry Cavill goes from Superman to super spy in The Man From U.N.C.L.E., and ET went behind the scenes of the action flick -- a throwback to the coolest era in American history.
Based on the '60s TV show, The Man From U.N.C.L.E. follows CIA agent Napoleon Solo (Cavill) and KGB agent Illya Kuryakin (Armie Hammer), who are forced to put their hostilities aside and work together to defeat a mysterious criminal organization with plans to use nuclear weapons and cause a global catastrophe.
Cavill admitted that there are definitely some advantages that his current role has over playing the Last Son of Krypton.
"There were definitely difficulties with that particular costume, which I don't have with this costume," the 32-year-old actor told ET. "It's just nice to be playing something different."
The period clothing was also a plus for co-star Alicia Vikander.
"You do have more fun when you're around well-dressed people," she said. "I don't know how many dresses that I've seen here that I would just love to bring back home."
Another upside for Cavill was the location. The British born actor was relieved to be shooting in the U.K.
"It's great to be working in England," he said. "I do like being home."
The film's director, fellow Brit Guy Ritchie, also enjoyed the comforts of his homeland, but the location proved to be troublesome when it came to keeping a reasonable curfew for his lead actors.
"Let's just say there's a lot of fun to be had in London and I think we've tried it all," Hammer said with a smile.
The Man From U.N.C.L.E. opens August 14.
