This movie had a group of people (3-4?) exploring an asteroid, planet, or maybe small ship. They encountered a tall, tall rectangle doorway that glowed bright white. They entered and it was completely white all around them. They had some sort of epiphany and it felt really beautiful.
I don’t remember the actors/actresses (I think one was a woman) and I don’t remember what happened to them. I feel like maybe the door was dangerous.
This was not an old movie, probably at least 1995 or newer. It felt newer than 2005 but I don’t want to restrict it too much!
I really want to watch it again. 🙂
Could be: Mission to Mars (2000) – http://www.imdb.com/title/tt0183523/
Skip to 1:11:00 for the doorway scene.
