We've seen a lot of amazing things during the promotional cycle for Captain America: Civil War, but one of the coolest elements came early on during Civil War's Superbowl TV Spot. A seemingly brainwashed Winter Soldier takes a deadly shot at Tony Stark that is miraculously stopped by an Iron Man gauntlet hidden in Tony's watch. As it turns out, this ingenious Stark invention came from the mind of Robert Downey, Jr. himself; Downey says that the gauntlet was actually his idea, and while the Russo Brothers apparently didn’t grab the idea at first, they eventually gave in. "Here’s why I love the Russos: that was not in the script. And I said, ‘What if I had this watch that kind of turned into a glove?’ They humored me for a couple of weeks, but I kept bringing it up. Eventually they had someone measure me for the hand-glove."
Don't worry, the device isn't actually called the "hand-glove"; it apparently doesn’t have a name. Despite the Russo Brothers not generating this idea themselves, it's certainly wonderful to know that they are open to some input from their cast. Given that Iron Man has had a briefcase suit, it's not so far fetched that he might keep a watch gauntlet on him as a protective measure, especially with someone like the Winter Soldier on the loose! It's interesting to think of how the scene was written prior to Downey's input; that look of shock on his face was certainly a highlight!
