Tonight's episode of Constantine saw Jim Corrigan introduced, played by Emmett J Scanlan.
It was a pretty great episode, which saw Corrigan team with Constantine, Zed and Chas to put down three spirits mistakenly brought back from the dead by Papa Midnite.
During the episode, Zed managed to get a reading from Jim Corrigan revealing his future alternate persona - The Spectre!
Check out the clip from the episode below.
It's possible we may get a Spectre spinoff series as show creator, David S. Goyer, stated as much back in July.
