On Sunset Boulevard, where a geodesic dome has stood as a cathedral of cinema since 1963, a six-year silence is coming to an end. Sony Pictures Entertainment has announced the restoration of the Cinerama Dome — a theater that was never merely a building, but a promise about what moving images could do to the human senses. The decision to revive it, under the stewardship of Alamo Drafthouse, arrives at a moment when audiences are quietly reasserting something the streaming era tried to argue away: that some experiences belong only in the dark, together, on a curved screen eighty-six feet wide.
