In the film Gentlemen Prefer Blondes, Marilyn Monroe purrs: “Men grow cold as girls grow old / And we all lose our charms in the end”. But 60 years after her death, the charms of Hollywood’s ultimate blonde bombshell have barely faded.

Netflix recently released a trailer for its biopic, Blonde, starring the Cuban actress Ana de Armas. In it she cries in front of a mirror before switching on the megawatt Monroe smile.
