Shipp will guest star in the pilot in a mystery role. If The Flash is ordered to series, Shipp’s character will likely recur.

The project — a spin-off of The CW’s Arrow — stars Grant Gustin as the titular crimefighter. The cast also includes Candice Patton (as Barry Allen’s best friend Iris West), Jesse L. Martin (as Barry’s father figure — and Iris’ dad — Central City Detective West), Carlos Valdes (as engineering genius Cisco Roman), Danielle Panabaker (as bioengineering expert Caitlin Snow), Rick Cosnett (as Detective Eddie Thawne) and Tom Cavanagh (as S.T.A.R. Labs scientist Harrison Wells).
