The Guardians of the Galaxy stars all got schooled…by a 5-year-old girl! On Monday’s Jimmy Kimmel Live, Zoe Saldana, Chris Pratt, Dave Bautista, Vin Diesel and Bradley Cooper all faced off with pint-size Marvel Comics expert Mia Grace, and let’s just say that little lady put these superheroes to shame with her impressive trivia knowledge! Not to worry, though: Guardians of the Galaxy doesn’t hit theaters until next Friday, August 1, so Zoë, Chris, Dave, Vin and Bradley have some time to brush up on their Marvel knowledge before they light up the big screen!
