- Most of the external shots of the Poseidon were shot using a model built from the original blueprints of the Queen Mary. The model is on display at the Los Angeles Maritime Museum at the Los Angeles harbor. The real Queen Mary is located just a few miles away in Long Beach.
- Shot in sequence, taking advantage of the fact that the principals became dirtier and more tattered and suffered injuries - some real and some artificial - as they progressed.
- Some of the pre-capsize sequences were shot aboard the Queen Mary, including the opening storm sequence, the pre-disaster scenes in the staterooms and hallways, the scenes above decks, and an early scene in the engine room.
- In the scene in which Rev. Scott rescues Robin, the set was built on tracks which would slowly lower the inclined set into a large water tank. The set was supposed to stop moving once the set was half-submerged, but for some reason it continued until the camera crew was underwater. The film magazine was rushed to the lab, where immediate processing showed the film was undamaged.
- The original script called for Rev. Scott to send Mrs. Rosen on her underwater mission, and for her to be trapped and need rescuing by him. Gene Hackman decided that his character would never ask her to do this, and suggested their characters' situations be reversed. Director Ronald Neame agreed, and they persuaded Shelley Winters that this was indeed better for her character.
