Constantine is one of DC's most iconic comics, and one of the few to make it to the big screen. The story is now in its second airing on the small screen, and already the executive producer is thinking about the future and what it could entail.
According to David S. Goyer, there is a possibility the character Swamp Thing could appear in the show. However, this is something that would take time, so fans should not expect to see Swamp Thing in the first season.
Goyer explained that bringing Swamp Thing to TV would be expensive, and the team is not interested in short-changing the character. Basically, there's no point in bringing Swamp Thing if the budget available right now is not capable of bringing the character to life in a way that is believable.
