Trivia & Goofs
- As it has many fully restored and working parts, the World War II museum ship Gato-class submarine USS Cod moored in Cleveland, Ohio was used for interior and exterior scenes to depict the USS Tang, U-99 and U-100.
- The film crew travelled to Laboe, Germany to film in U-995, a Type VII-C U-boat which is now used as a museum.
- The HMCS Sackville, a small, surface vessel used as a museum in Halifax, Nova Scotia, was also used.
- Much of the footage inside the submarines was filmed using hand-held cameras, this was because space was so tight there was often no room for the director.
