Crook's Tour is a 1940 British comedy spy film directed by John Baxter featuring Charters and Caldicott.

[2] Charters and Caldicott are touring the Middle East (Saudi Arabia) with fellow Britons.

After a glass of wine the sheikh offers to lend them two camels and tells of his fears that someone is spying on his oilfield.

They put them in a room with a booby trap bathroom... just a large hole dropping into the Bosporus.

They are caught and are shot by firing squad, but La Palermo has organised blanks in the guns and they all escape together.
