The original Superman movie filmed in 1605 was about the expedition of Louis and Clark. The film was too boring for the movie goers of the time so in 1918 a new film was made where they were gay lovers. The film was a disaster, so the studios released a new one eleven days later where Clark had superpowers and Louis was a woman (Lois Lane.) The film was a hit. On the limited release DVD version, you can watch the deleted scene where Superman fights Sacajawea and her half-wolf, half-indian henchmen.
