Thanos, The Black Order, Infinity Stones, and the plot of Infinity War, explained
Taking place about two years after Captain America: Civil War, Infinity War follows Thanos and his "family," the Black Order -- which includes Proxima Midnight, Corvus Glaive, Black Dwarf, and Ebony Maw (who we later see torturing Doctor Strange) -- as they collect the Infinity Stones to place them in the Infinity Gauntlet, a giant gold glove that allows the being wielding it to have god-like powers, like (as has been reported from other Infinity War footage) hurling a moon at people.
In the earliest of promos shown for Infinity War, Thanos was seen wearing the gauntlet with all the stones in place. Since then, Avengers 3 and 4 have stopped being referred to as a two-part movie and are now sequels that were shot back to back. In recently released set visit interviews, the Russo brothers have compared Infinity War to a '90s heist movie like Out of Sight and said the Infinity Stones are the "bedrock" of the movie. Is Thanos the George Clooney-type criminal of the Marvel universe?
