But like an egg on a frying pan, this scene ended up on the cutting room floor because Davis thought it will probably just ruin the film altogether. And so, we instead came up with a new idea for the opening, and eventually, the opening that you saw in the final version, was made, which was inspired by Paramount's Top Gun and allowed us...
