'Just to give you a general idea,' he would explain to them. for Central London always made a point of personally conducting his new students round the various departments. Each of them carried a notebook, in which, whenever the great man spoke, he desperately scribbled. A troop of newly arrived students, very young, pink and callow, followed nervously, rather abjectly, at the Director's heels. 'And this,' said the Director opening the door, 'is the Fertilizing Room.' Bent over their instruments, three hundred Fertilizers were plunged, as the Director of Hatcheries and Conditioning entered the room, in the scarcely breathing silence, the absent-minded, soliloquizing hum or whistle, of absorbed concentration.

Only from the yellow barrels of the microscopes did it borrow a certain rich and living substance, lying along the polished tubes like butter, streak after luscious streak in long recession down the work tables. The overalls of the workers were white, their hands gloved with a pale corpse-coloured rubber. Cold for all the summer beyond the panes, for all the tropical heat of the room itself, a harsh thin light glared through the windows, hungrily seeking some draped lay figure, some pallid shape of academic goose-flesh, but finding only the glass and nickel and bleakly shining porcelain of a laboratory. The enormous room on the ground floor faced towards the north. Over the main entrance the words, central London hatchery and conditioning centre, and, in a shield, the World State's motto, community, identity, stability. I guess the nature of the scene and the logistics made them opt for a cheaper location.A squat grey building of only thirty-four stories. It is actually a tunnel in Prospect Park, Brooklyn called meadowport arch. Okay, so another our later and I found it.

I guess because of he shocking nature of the scene. As a matter of fact, not one site mentions it. This site doesn't mention anything about the tunnel either. However, after going over the list of every tunnel (including the one closed now for storage), I didn't find the one that resembles it. I do think however the tunnel from the Brave One and from The Immigrant are the same. You can pause the trailer and check it out. It has benches on the side and large slabs agains the wall.
