i noticed this if u have seen the entrence to disaster facade it's kinda of a steel door
and this is a clip of the treatment for the beginning of run:
As you enter the dark cave-like structure, you are met with the sight of a rusted metal archway. Lights surround the word “RUN”. As you move underneath the archway, a gaunt GAME SHOW HOST slams a STEEL DOOR shut behind you triggering a blinding green light. A loud air-horn shrieks the beginning of the game followed by an ominous voice that screams a single command at you. “RUN!!!!!!”
