Truly mind-expanding in its own button-down way. The unusual pace is set right in the opening, an eerie shot of a disembodied eyeball - no credits, no production logo, just an eyeball. There's more than just trippy imagery and cheap thrills here, though - the themes are cosmic, and the dialogue is richly layered with references to sight and lack thereof. Even the purpler soliloquies (like the one about "a city unborn"), which coming out of a lesser actor's mouth might seem like a simple necessary way to cut production costs (telling is usually cheaper than showing, depending on the actor), seem powerful and significant when delivered by Ray Milland.
