As long prophesied in some ancient book deep within The House Of Mystery—and also this Newswire—the snarky, cynical, chain-smoking, Sting-looking demon hunter known as John Constantine will officially be crossing over into the world of The CW’s Arrow during its upcoming fourth season. Not only that, but Constantine will be played by Matt Ryan, reprising his role from NBC’s short-loved (and reasonably well-liked) Constantine TV series. According to Variety, CW president Mark Pedowitz referred to Constantine’s appearance as a “great one-shot episode,” so it doesn’t sound like he’ll be sticking around and becoming a new love interest for any of the regular Arrow characters. Still, this will hopefully be a nice consolation prize for the Constantine fans who are mad at NBC for dumping the show back in June.
