Trivia / Joe Versus the Volcano

• Acting for Two: Meg Ryan plays three different characters: Joe's co-worker Dede and half-sisters Patricia and Angelica. They are to meant to symbolize the changes of the same woman someone met during its life according to the filmmakers. As a side note, she also voices the intercom announcement on the American Airlines plane.
• Spared by the Cut: In the original ending, the chief of the island where the volcano goes off and the crew of Patricia's sunken yacht all turn up alive and are picked up by a rescue ship along with Joe and Patricia. The final cut ends without showing any of this, implying that all of those characters are dead.
