You may have already noticed that the common story in two of this year’s biggest films is of heroes who become sworn enemies. In one corner, we have Batman V Superman, with the Caped Crusader and the Man of Steel locked in a furious battle seemingly orchestrated by Lex Luthor. In the other there’s Captain America: Civil War, which sees the Avengers split into two opposing factions – one supporting a government register for those with super powers, the other against it. A similar rift appears to be opening up in the film industry – this time over a new streaming service called Screening Room. Proposed by Napster co-creator Sean Parker, Screening Room will, if it goes ahead, allow its subscribers to watch brand new films in their living rooms on the same day they come out in cinemas.
