The Lady in the Car with Glasses and a Gun (French: La Dame dans l'auto avec des lunettes et un fusil) is a 1970 psychological thriller film directed by Anatole Litvak starring Samantha Eggar, Oliver Reed and John McEnery.

Just before the Bastille Day holiday weekend, English secretary Danielle "Dany" Lang types up a document for her advertising agency boss, Michael Caldwell, to take on a business trip to Geneva.

After Philippe disappears again, Dany visits the home of the dead man in Avignon and oddly finds both some of her clothes and also nude pictures of herself.

Roger Greenspun in his New York Times review said that "in relation to better works in its genre, the film looks rather like an example of the decline of craftsmanship — effective, well-colored, but uncertain in line and construction."

"[4] New York Magazine said "the Japrisot thriller has become an incoherent mystery with antiquely heavy handed performances by Oliver Reed, John McEnery and Samantha Eggar.
