The Deep Six

The USS 'Poe' ship in this film was portrayed by the real-life Fletcher Class destroyer DD-538 USS 'Stephen Potter' for this movie. This vessel was named after World War I naval aviator Ensign Stephen Potter (1896-1918). The ship was chosen because of it was used during the Second World War. It was commissioned in October 1943. During the war it was mostly used to screen the fast carrier task groups. It was mothballed in September 1945. It was recommissioned in 1951 and served until 1958 until it was mothballed again. It was scrapped in 1973. The ship earned 12 battle stars for its service in World War 2.

At the end of Susan's first visit to Alec's place, one reason she says she must leave is because it is quite late. And it was indeed dark out when she arrived, but it is clearly daytime when she leaves. The scene was obviously filmed during the day. Perhaps processing was supposed to correct this error.
