English: One of the highlights of Expo 67 was the Labyrinth Pavilion by the NFB. A five-storey building with two screening halls and a transition hall. Designed by producers and filmmakers Colin Low, Roman Kroitor and Hugh O’Connor, the pavilion brought to mind Daedalus’ labyrinth where Theseus killed the Minotaur. But what was inside this Labyrinth?

The audience was invited to a first screening in Hall I. Standing on eight balconies spread over four floors, they could see on two screens, measuring eleven-and-a-half meters by six meters each, one installed on the ground, the other set up vertically, images symbolizing the entry of man into the world, the innocence of childhood and the joie de vivre of adolescence. Two hundred and eighty-eight speakers arranged behind the screens ensured a sound experience that had been unmatched until then.

Then they crossed Hall II, a transitional space filled with colour and music evoking the mazes of a labyrinth before reaching Hall III.

It was this last hall that held the highlight of the show! A film projected simultaneously by five projectors on five large screens arranged in the shape of a cross. A sensory experience so unprecedented that it would closely match what IMAX technology would offer years later. Filmed in Ethiopia, Japan, Cambodia, the United States, Greece, India, the United Kingdom, Canada and the former USSR, which at the time was a feat, In the Labyrinth (1967) was intended as a modern interpretation of the myth of Theseus and the Minotaur.
