**FULL SPOILERS FOR CRISIS ON INFINITE EARTHS***
Last night was the finale to this year's Arrowverse crossover called Crisis On Infinite Earths and MY GOD we got BOTH versions of The Flash from the movies and television show in the SAME SCENE!
During Part Four or the Arrow episode of the crossover we saw Barry talking to a "SpeedForce version" of Oliver before running off and bumping into Ezra Miller's version of The Flash at S.T.A.R. Labs. The even cooler thing was that Ezra Miller was in his full Flash costume from Justice League in 2017.
I won't spoil how the scene plays out, but you can check it out below. However, this means that the Arrowverse is a parallel universe to the DC movie universe (referred to by fans as the DC Extended Universe or DCEU) where Miller’s Flash resides and the events of Man of Steel, Batman v Superman: Dawn of Justice, Justice League, Suicide Squad, Wonder Woman, Aquaman, and Shazam! took place!!
