So overt it’s covert. That’s how the famous detective explains away the crassness of his disguises. In this newest instalment of the latest cinematic incarnation of the Holmesian myth, the detective rummages through the dressing-up box for silly beards, false gnashers, stupid specs. This Holmes even wears a type of babygrow whose patterning comically blends into the decor. As with Sherlock Holmes, so with Sherlock Holmes: A Game of Shadows. This is another film by Guy Ritchie disguised as a detective story by Arthur Conan Doyle. You couldn’t ever mistake it for the real thing.

My Week With Marilyn depicts the supposedly sweet dalliance between Marilyn Monroe - an actress in over her head played by an actress, Michelle Williams, reaching her peak - and eager-beaver gofer Colin Clark (Eddie Redmayne) during the fraught Pinewood production of Laurence Olivier’s The Prince and the Showgirl in 1956.
