Possible Flash Details
The Flash film has been wracked with difficulties ever since it was announced. Multiple directors and writers have been attached to it and its release date pushed back from 2018 to 2020. The Reddit post claims that the Rogues will be the villains for the film and that Double Down will join them.
Double Down is a super-villain that bonded with a mystical deck of playing cards. After losing a game, Double Down murdered the cards original owner. The cards replaced most of his skin and can be mentally controlled to fly and cut like a razor. The Reddit user says DC would like Walton Goggins to play Double Down.
