I See a Dark Stranger (U.S. title: The Adventuress) is a 1946 British World War II spy comedy film directed by Frank Launder and Sidney Gilliat and starred Deborah Kerr and Trevor Howard.

Frank Launder and Sidney Gilliat, writers who had worked on Alfred Hitchcock's 1938 spy film The Lady Vanishes, formed Individual Pictures in 1945.

I See a Dark Stranger was the first of ten films released by the company, with Launder kicking off an intended rotation between the pair as director.

[1] The picture was filmed at various locations, including Dublin, Dundalk and around Wexford in Ireland, Dunster in England, and the Isle of Man.

[1][2] During production, a rumour spread among crew members that a close relationship had developed between the "handsome, young" cinematographer Wilkie Cooper and Deborah Kerr.

If it went beyond that, the affair was short-lived, as Kerr married Spitfire pilot Tony Bartley almost immediately after the film's completion.

[3] Charters and Caldicott, characters Launder and Gilliat first introduced in The Lady Vanishes (1938), were set to appear in the film but due to a disagreement with the actors Basil Radford and Naunton Wayne they were replaced by Captain Goodhusband and Lieutenant Spanswick.

[4] The film was released in the United States under the title The Adventuress, to good reviews but modest box office.

"[5] Deborah Kerr won a 1947 New York Film Critics Circle Award for Best Actress for her performances in Black Narcissus and I See a Dark Stranger.
