Battle Hell

The River Orwell, which runs between Felixstowe and Ipswich in Suffolk, England doubled as the Yangtze River during the making of this film.

Towards the end of the film, shortly before Amethyst rejoins Concord, we see a scene with Kerans standing on the bridge of Amethyst. The scene in the background is obviously a still image painted on the background. The waves are static. There is, however, light smoke which is moving between the bridge and the sky.

Opening credits prologue: The story of H.M.S. Amethyst is true and this dramatic reconstruction of it was shot with all possible accuracy in and aboard Amethyst herself. The producers' apologies are due, however, to the officers and ships' companies, the Chinese interpreter and many others whose parts in the original action have not been portrayed. These omissions have been dictated solely by the limitations of screen time. To the Admiralty, the War Office and the Air Ministry, to Commanders-in-Chief, Officers and Ratings of H.M. Ships and other naval establishments who have contributed so much to the making of this film, the producers tender their sincere thanks.
