That is, if The CW renews the comic book drama.

Constantine may live again.

After reprising his role as John Constantine during the current third season of The CW's Legends of Tomorrow, Matt Ryan could return in a full-time capacity. Should The CW renew the Arrow-verse drama for a fourth cycle, the actor would return as a series regular.

Ryan originally played the DC Comics character for one season on NBC's since-canceled live-action Constantine. He later appeared in season four of Arrow before booking two arcs on Legends.

Despite NBC's cancellation, Ryan has remained committed to the part and voices the role in the CW Seed animated series Constantine, which will debut Saturday on the digital platform.

"We knew that an alienated, chain-smoking, bisexual, world-weary demonologist would feel right at home among our Legends," Legends showrunner Phil Klemmer told The Hollywood Reporter in October ahead of Ryan's debut on the series.

Should Legends earn another season, Ryan would help replenish the show's ranks of series regulars after losing Wentworth Miller, Victor Garber and Franz Drameh this season.

Ryan is repped by Gersh, Jackoway Tyerman and the U.K.'s Curtis Brown Group.

Legends of Tomorrow has been a sturdy player for The CW this season and is expected to return, especially as the younger-skewing network is expanding to a sixth night of programming (Sundays) for the 2018-19 season.
