The Flash Welcomes Back Mark Hamill (and His Classic Trickster Costume) in New Trailer

Must be a trailer for the return of The CW’s The Flash, which is back next Tuesday.

The rest of the season promises to be even bigger in scope, as more and more Rogues come together, time travel becomes a big part of the series and the hunt for the Reverse-Flash comes closer to home. 

Check out the trailer below (via People.)

The Flash returns next Tuesday, March 17, at 8 p.m. ET/PT on The CW.
