Lexi Alexander to Direct Supergirl Episode 14, Featuring The Master Jailer

Punisher War Zone and Arrow director Lexi Alexander will ply her trade on the upcoming, fourteenth episode of Supergirl, which will feature the Master Jailer.

Jeff Branson has been cast in the recurring role of Master Jailer. As the forceful and unrelenting jail guard on Fort Rozz, Master Jailer showed no mercy. Now on Earth, he is hellbent on catching all of the Fort Rozz escapees and brutally bringing them to justice.

The announcement was made today during Warner Bros. Television's Supergirl session at the Television Critics Association Winter 2016 Press Tour on the Warner Bros. Studios lot.

In the comics, Master Jailer battled Superman -- but also worked for S.T.A.R. Labs and later Checkmate under various names, including Deathtrap and Castelian, as a security consultant who would legally and legitimately capture villains.
