The Blindfold glitch turns the entire screen black, and won't display ANYTHING except for a once in a while flash(as seen in the movie), until you hit the start button. To do it, you press start and walk into a door when the screen is pitch black.

In the movie, Samus first gets the glitch to work (which takes a while), then goes to the right. 3 'pshew's are heard, that's Samus killing the eye-door. Then some lasers, and Samus enters. The door closes, and another one opens a bit later. Samus enters it and that one closes. She's now in the save point(I had to organize my thoughts for what to do next). After a break, Samus continues down, and opens the door with 5 missles. Heading in, she blasts one barrier after another. I lost count of barriers, though, and started running into Mother Brain thinking she was a barrier. After I realized it though, I started firing again, and she's eventually on the ground. She gets up, and I switch to laser. It is actually easier to beat her with them, only 16 shots. She uses her mind attack, and Samus's down, the metroid takes Mother Brain down, heals Samus, dies, etc. Then Samus finishes off Mother Brain. There. That's over. Samus goes left when the time bomb starts up, blasts through after a bit of confusion(I still don't know what kept me from going in the door), and you catch a brief snip of a door, and a timer. Samus continues on to the right, and I got the rooms mixed up. I thought I was in the HUUGE room where lava begins to rise when you're half way through. After a bit of confusion I realize where I am, then do a super jump in the bottom right corner. After that, I TRIED to go up the wall, but I didn't make it. Finally, I hit start to undo the glitch. The rest you can see for yourself.
