DC’s Legends of Tomorrow must like that voodoo he do as John Constantine, because Matt Ryan is set to join the CW series as a series regular in the event of a Season 4 renewal.

Having fronted his own Constantine series for NBC during the 2014-15 TV season, Ryan first dipped his wand into The CW’s #DCTV universe with a Season 4 appearance on Arrow. Tonight he makes his second of three Season 3 visits to Legends, as Constantine is presumably called on to help keep Sara out of the demon Mallus’ grasp. With Ryan as a Season 4 cast member, John would join the team members aboard the Waverider.

Ryan also voices Constantine for an animated series that launches on CW Seed this Saturday, March 24. [Source]
