Beginning tonight, The CW is celebrating DC Week to mark the return of The Flash and Arrow, and the premiere, later in the week, of DC's Legends of Tomorrow.

The Flash debuts new episodes tonight at 8 p.m. ET and, as if that didn't have you excited enough, Arrow returns with all-new episodes tomorrow!

But there's more:  Tonight after The Flash, tune in to The CW for a couple of sweet specials–DC Legends of Tomorrow: Their Time is Now and DC Films Presents: Dawn of the Justice League–to get you ready for Thursday's Legends premiere and an advance look at the new Suicide Squad trailer.

Check out the trailers below, and be sure to tune in tonight beginning at 8 p.m. for the return of The Flash.
