Swamp Thing has already started production and Matt Ryan’s John Constantine is wanting a part in it. At a recent appearance at Wizard World Cleveland, Ryan stated that he hopes to play John Constantine in the upcoming DC Universe TV series Swamp Thing.
“John Constantine was born in Swamp Thing. Eventually, he has to be on Swamp Thing, and I just hope it’s me,” Matt Ryan stated. “I’m still playing this role four years after Constantine was actually canceled, so I must be doing something right”.
In the comics, John Constantine first appeared in The Saga of Swamp Thing #37 in 1985. Constantine becomes fascinated with the creature and later acts as the Swamp Thing’s protector, guide, and even helped amplify its powers. John Constantine would eventually go off to having his own popular, long-running series and he continues to remain in DC comics today.
Although the John Constantine TV adaptation was cancelled after the first season, Ryan has remained committed to the role of John Constantine and has made several appearances in the Arrowverse.
The chances of John Constantine appearing in Swamp Thing does seem very likely. However, seeing how things have gone for him in the past, the chances of Matt Ryan playing the role of John Constantine seems very slim at this time.
