Thor may not be the only one worthy of wielding the hammer Mjolnir in the Marvel Cinematic Universe. The hammer was previously owned by Thor's father Odin (Anthony Hopkins) in the first 'Thor' movie. The android Vision (Paul Bettany) has used Mjolnir in 'Avengers: Age of Ultron' and even commented about its balance.

'Avengers: Age of Ultron' also featured a scene where the other Avengers tried to lift the hammer from a coffee table. Tony Stark (Robert Downey Jr.) and James Rhodes (Don Cheadle) even joined forces to get Mjolnir to budge. However, it was Captain America (Chris Evans) who managed to move the hammer just a tiny bit, just enough to make Thor (Chris Hemsworth) take notice.

It looks like Steve Rogers will be doing more than just making Mjolnir move an inch in the upcoming 'Captain America: Civil War.'

The SuperHeroHype message boards recently went viral when a user known as Charleswelsh posted about sneaking into the 'Captain America: Civil War' set and leaked some information about a certain superhero holding a certain prop. Charleswelsh started the post by sharing how easy it was to get into the set. He even decided to sit down and have lunch from craft services. He later encounters Evans and Elizabeth Olsen, who will play Scarlet Witch in the movie.

Then he discovers something interesting.

"After most of the important folks cleared out, I decided I had enough excitement and walked back to work," he wrote. "One interesting thing I noticed while they were preparing for the stunt, was Captain America waving around a CGI stand-in prop that was shaped like a double sided hammer. Do you guys think that means he's going to get his hands on Thor's hammer in this movie? "

The post not only confirmed that Captain America will finally wield Mjolnir, but also a possible appearance by Thor in 'Civil War.'

'Captain America: Civil War' will be released on May 6, 2016.
