I have already analyzed every single movie he ever did, including co-stars, directors, release dates and cross-checked them with the opening of the Golden gate bridge, the day when the Golden Gate entered 266°, 72 years later when the Golden Gate entered 267°, the Golden Gate tetrad midpoint, the September Eleven attacks and a couple of other events. I have also checked his advertisements, his video clips (Don't Worry, Be Happy). Besides the obvious symbolism, there are many magic numbers and Golden Gate numbers among them. I hope to post more about it bit by bit.
Robin Williams died very similar like the boy in "World's Greatest Dad", with t a belt around his neck hanging from a door knob. No autoerotic stuff was reported though.
Stay tuned for more!
