CW Pushes Towards Season Finales with "Flash" Trailer, Black Canary Poster

There are four episodes left in the first season of "The Flash" and three episodes left in the third season of "Arrow," and as such, The CW is ramping up promotion of its DC Comics-based hits. On Monday, the network released both a poster featuring "Arrow" character Black Canary/Laurel Lance (Katie Cassidy) and a new 45-second teaser for the final episodes of "Flash" season one.

The poster is the latest in a series, which has previously featured The Flash (Grant Gustin), Arrow (Stephen Amell) and Arsenal (Colton Haynes) and the Dark Archer (John Barrowman) and Reverse Flash (Tom Cavanagh).

The new "Flash" teaser further promotes the impending conflict between Flash and Reverse Flash, plus contains hints of Grodd, a team-up with Arrow and Firestorm (Robbie Amell) and more.

"The Flash" airs 8 p.m. on Tuesdays, "Arrow" airs 8 p.m. on Wednesdays; both on The CW.
