For one night the boulevard stops belonging to tourists and belongs entirely to the movies. Traffic gone. Barricades up. Four blocks of Hollywood under the attention of most of the planet at once.
People forget the ceremony has an outside. The fan zone along the carpet approach is a real thing you can stand in — registered spectators watch the arrivals from designated areas, and registration opens on the Academy's site weeks ahead and fills within hours. The street shuts to through traffic that morning, the Dolby's entrance becomes the carpet, and the surrounding blocks turn into perimeter and infrastructure. The whole neighborhood takes on the particular charge of a night the world is watching your city block.
Downtown Hollywood, Metro to Hollywood and Highland, free to observe from the public areas outside the perimeter.
