Constantine TV Show Teases Swamp Thing

NBC has just released a new photo for the Constantine TV series, and it includes a tease for Swamp Thing.

Through the official Constantine Twitter account, NBC tweeted the image above, along with the text, "Experiencing a demon problem? Call John #Constantine, Master of the Dark Arts at 404-248-7182."

When you dial the number, a recording says, "Hello, you've reached John Constantine. And that's John Constantine. If you're looking for Alec Holland, try the bloody swamp."

Of course, Alec Holland is the man who became Swamp Thing. Is it just a cool Easter Egg? Or could Swamp Thing actually appear on Constantine?

Constantine premieres on Friday, October 24th, 2014 at 10 PM ET/PT on NBC.
