During the making of which film did actress Jill Ireland meet her second husband Charles Bronson?

Jill Dorothy Ireland (24 April 1936 – 18 May 1990) was an English actress and singer. Born in London, Ireland was the daughter of a wine importer.

In 1957, Ireland married actor David McCallum after the couple met while working on the film "Hell Drivers" (1957). Later, they appeared together in five episodes of "The Man from U.N.C.L.E.". They had three sons, Paul, Valentine, and Jason (who was adopted). McCallum and Ireland divorced in 1967.

In 1968, Ireland married Charles Bronson. She had met him when he and McCallum were filming "The Great Escape" (1963) some years earlier. Together they had a daughter, Zuleika, and adopted a daughter, Katrina. They remained married until Ireland's death in 1990.

"The Great Escape" is a 1963 American epic war film starring Steve McQueen, James Garner, and Richard Attenborough and featuring James Donald, Charles Bronson, Donald Pleasence, James Coburn, and Hannes Messemer. It was filmed in Panavision.

The film is based on Paul Brickhill's 1950 nonfiction book of the same name, a firsthand account of the mass escape by British Commonwealth prisoners of war from German POW camp Stalag Luft III in Sagan (now Żagań, Poland), in the province of Lower Silesia, Nazi Germany
