Trevor Howard once said of this movie: "The best thing about 'Cockleshell Heroes' was filming in Portugal. Beautiful country.

As for the film, well."

Lisbon stood in for Bordeaux.
Trevor Howard nearly drowned after the canoe he shared with David Lodge overturned and he found himself trapped under the water. Real life marines dived in and saved him.
