10 Unfilmed Movie Scenes That Explain Crucial Details

1. Ripley & Dallas' Relationship - Alien

Here's a scene that Ridley Scott evidently kept ahold of, given that it re-appeared in Prometheus, when Vickers and Janek decide to relieve some stress by hooking up in the crew's quarters.

This scene was originally scripted for Alien, and though it might not sound crucial in the most typical sense, it would've injected a little more humanity into the situation and told us something about the psychology of these characters. It featured Dallas relaxing while staring into space, when Ripley approaches him and suggests that she wants some.

The scene was filmed as a screen test - featuring an actor standing in for Tom Skerritt - though never actually committed to as a proper scene. It might not fill any plot holes, but it does provide some curious additional information about the characters.
