Over on the Super Hero Hype message boards, a user named Charleswelsh claims to have snuck onto the set in Atlanta, Georgia last Wednesday during his lunch break.
And while looking around, he claims he saw a scene involving Captain America and Scarlet Witch fighting soldiers at the Atlantic Civic Center, which has been made to look like the Institute for Infectious Diseases.
But what makes it really interesting is that, he said he saw a stunt being prepared that involved "Captain America waving around a CGI stand-in prop that was shaped like a double sided hammer." Cap couldn't lift Thor's hammer in Avengers: Age of Ultron, but he may have become worthy enough over time.
Or, this may not be a hammer at all, but some other weapon that Cap is using against the bad guys. And for now, it’s hard to know whether this story is legitimate or not, so take it with a grain of salt for the minute.
If Cap is in possession of Thor's hammer that opens up a lot of questions. Tell us your thoughts in the comments below.
