Captain America's shield is quite iconic, so much so that even other superheroes want a chance to wield it.
Throw Ant-Man and Captain America: Civil War's Paul Rudd into that category as well. In a recent appearance on The Late Late Show with James Corden, Rudd admitted to grabbing Captain America's shield from the prop guy while Actor Chris Evans was taking a bathroom break.
Even though he got to hold the shield, Rudd said he still felt like "I was cousin Oliver to the rest of the Brady Bunch" during filming. Regardless, he is probably going to have multiple scene-stealing parts in the movie, and even has some in the trailers, so he shouldn't get too down on himself.
