Forget Batman V Superman, it The Flash v The Flash that’s getting us really hyped thanks to this fabulous clip from episode 2.17, “Flash Back”. The superhero who has to fight himself has been a staple of comic for decades now (sometime via cloning, sometime via alien doubles, sometime via parallel worlds, and sometime, as here, via time travels) but it’s not done enough on screen. You can trust The Flash to bring it to live-action life in style, though – this is the show that loves embracing comic clichés and reinventing them.
The official synopsis reveals: “Desperate to find a way to increase his speed, Barry decides to travel back in time and masquerade as his earlier self in order to get his arch-nemesis, Dr Harrison Wells/Eobard Thawne (Tom Cavanagh), to teach him how to run faster. However, things don’t go as planned and Barry is stunned to face familiar foe Hartley Rathaway (guest star Andy Mientus), as well as old friend Eddie Thawne (guest star Rick Cosnett). Iris (Candice Patton) makes peace with her past in order to embrace her future.”
