Jesse L. Martin has joined the cast of The CW's Flash pilot, TVGuide.com has confirmed.
The Law & Order alum will play Detective West, an honest, blue-collar cop who is a surrogate father to Barry Allen (Grant Gustin). West is the father of Barry's eventual wife in the comics, Iris West.
The Arrow spin-off initially launched during the final episodes of sophomore series' fall run, when Barry traveled to Starling City to help on a case before he was struck by lightning mixed with chemicals in the midseason finale.
