Marvel has proven in recent times that comic book adaptations are hugely popular on the big and small screens alike, having huge success with its own-produced Avengers and tie-in movies. The second series of Agents of S.H.I.E.L.D. has garnered great viewing figures on its UK debut and the comic book company has signed a deal with Netflix top produced other TV shows based on its characters, including Daredevil.

Amazon has therefore struck a deal with rival comic company DC, owned by Warner, which is also currently undertaking an assault in cinemas and on TV screens with its own superhero and other adapted properties. And the UK market greatly benefits, with Constantine, about a British master of the occult and unlikely hero, being the first to be exclusively available on the streaming platform.

The series sticks more to the Hellblazer and current self-titled versions of John Constantine, rather than the Americanised alternative played by Keanu Reeves in the similarly named film.

It stars Brit Matt Ryan in the eponymous role and is co-produced by David S Goyer, one of the screenwriters behind the Dark Knight trilogy.
