Lolita was filmed on two continents with most of the action taking place in England

A second car was used for the scenes shot in the USA as Humbert Humbert drives around

Gettysburg appears at the very beginning of the film as he approaches Quilty's home

The station at which Humbert Humbert arrives is in Rhode Island

Other places used were Albany, Newport and Route 128

In England, the house where Lolita lives with her husband appears to be somewhere in North London and I assume that the hospital really existed

The area in which Humbert lives with Lolita and her mother appears to be a suburb of London
