Scandal

A title card says, "One Year Later, 1962," indicating Profumo addressed Parliament re Keeler that year.

But, Profumo's address was actually in March 1963.

When Christine arrives back at Heathrow from Spain after the scandal breaks, there's a modern illuminated sign in the background as she walks from the gate.

When Mandy Rice Davies and Christine Keeler are walking in the early morning alongside the river Thames, there is a modern 1980s coach crossing the bridge in the background.

Near the end of the film where Mandy Rice-Davies is surrounded by the press, one of the photographers - using a twin-lens reflex camera - has his finger on the lower (taking) lens at the moment of exposure.

No professional photographer would make this mistake.
