Carry on Admiral

Carry on Admiral released in the United States as The Ship Was Loaded is a 1957 British comedy film directed by Val Guest and featuring David Tomlinson and Ronald Shiner Joan Sims, who later became prominent in the Carry On series, has a small part. It predates and was not part of the Carry On series, and does not share any cast members beyond Sims, though it is similar in tone and style to the earliest films in the series. It was based on the 1947 stage play Off the Record, written by Ian Hay.

The fictional ship HMS Sherwood in the film is played by a Daringclass destroyer. Other ships shown include the battleship HMSVanguard and the frigate HMSPaladin during the title sequence, two Didoclass cruisers in early background scenes, and a Lochclass frigate during the closing credits. Several scenes were filmed in Admiralty House, in Portsmouth Naval Base.
