While you were at home enjoying the Super Bowl and the movie trailers that came with it -- including spots for Avengers: Age of Ultron and Jurassic World -- the stars of those two summer 2015 blockbusters were at the big game.
Chris Evans and Chris Pratt attended together and even had a wager on the outcome, because the former was rooting for the New England Patriots while the latter is a Seattle Seahawks fan. The Patriots won, but the stars have settled their bet as a draw, meaning they'll both visit children's hospitals in the respective teams' cities in costume as their Marvel-cinematic-universe characters.
On top of that, Evans and Pratt joined up with Jimmy Fallon to add even more fun to the greatest American sporting event of the year. The trio photobombed pictures being taken of people on the NBC Sports red carpet, acting all crazy behind the unsuspecting attendees.
Once in a while the posing fans noticed the shenanigans and turned around, though more of them seemed to recognize Fallon better than the movie stars. Other times, we guess these lucky folks were surprised to see celebrities behind them climbing or jumping all over each other. Or doing obscene things with sandwiches.
