Often dubbed the scariest horror film ever made, Psycho tells the story of disturbed motel owner Norman Bates – and his grisly encounter with criminal secretary Crane.

As many TV addicts will know already, a Psycho spin-off, Bates Motel, has been painstakingly detailing the backstory of Norman Bates (Freddie Highmore) and his mother, Norma (Vera Farmiga).

Now in its fifth season, the storyline is finally getting into canon we know, love, and are terrified by: Norma is but a stuffed corpse, Norman is spiralling ever deeper into his delusions and Marion Crane has finally checked into her room.

Enter Rihanna, dressed – slightly bafflingly – in a velvet cape. Not great rain attire, RiRi...
