528491 is an important number in the movie Inception. In the film, one of the main characters, Robert Fischer, states the number as the "password" of the safe inside of Fischer's subconscious. In actuality, the number is just Fischer's subconscious creating the number so that the team can gain access to the safe.

The first and last 3 numbers are significant in the film as well, the former being the most as it is the room code of the team where the explosives will be set off below, in 491. 491 is more commonly known as a representation of the "unforgivable sin" committed by Dominick Cobb.

528491 is also part of the soundtrack in Inception, notably played in the climax when Fischer discovers the idea plant, or as Fischer's mind puts it, his father's "last will".
Cobb: "Give me the first six numbers that come into your head right now."

Fischer: "I have no idea."

Cobb: "RIGHT NOW! I SAID RIGHT NOW! points his gun at Browning's head RIGHT NOW!"
