Forbidden Planet 4K UHD Review: Welcome Back to Altair IV in Glorious CinemaScope

While not the first big-price-tag science fiction film to come out of Hollywood, 1956’s Forbidden Planet certainly shook up the world of fantasy filmmaking. Set on the alien planet of Altair IV, the story is based on William Shakespeare’s The Tempest, where a reclusive scientist, his naïve daughter, a mechanical servant, and a mysterious monster mirror the play’s core characters and dynamics. Upping the ante were the thrilling possibilities of the faster-than-light C-57D saucer, arriving to search for survivors of a mining crew dispatched some 20 years prior. What they find are the remnants of a long-lost native civilization, advanced beyond the dreams of mankind but wiped out for reasons no one yet understands. Their technology is still very much operational, however, unleashing a force that puts everyone in grave danger.

It’s hard not to view Forbidden Planet through a modern lens, largely because we’ve spent the past 70 years evolving past the tropes that this movie established so indelibly. There’s nothing “B-movie” about the concept or execution; it was made on a then astronomical budget (see what I did there?) of $2M, the first time a major studio poured prestige level dough into a space adventure. Robby the Robot alone cost a reported $125,000! The production values shine in the elaborate sets (it wasn’t shot on location on Altair IV) and the special effects, a dazzling combination of miniatures, matte paintings, animation, and practical trickery. The intense acting, unserious character interplay, and “romance” will no doubt play as corny to first timers, but we also explore some intelligent themes, including the darkness of the mind and the folly of so-called genius, and it’s all quite a bit of G-rated fun.

A new restoration was undertaken by Arrow Films from the original camera negative and is presented here at the full 2.55:1 aspect ratio, with Dolby Vision high dynamic range. That extra bit of width comes courtesy of early magnetic track CinemaScope, shortly before the industry switched to optical audio film prints, which would take a bite out of the frame’s real estate. This is, in fact, the first time that Forbidden Planet has ever been released on home media in its proper CinemaScope ratio. The enticing Eastman Color palette was no doubt intended to lure audiences off their sofas and into the theaters, rife with blue eyes and green skies. Shadows are natural and nuanced, and the grain is maintained but not distracting.

The restored lossless original mono is the default audio, followed by “Perspecta” stereo and a modern 5.1 channel option. Perspecta deserves a shoutout for its obscure and unusual approach, essentially moving the mono soundtrack between the left, center, and right front channels to enhance the experience in a crafty, if slightly disingenuous, manner. While the clarity and fidelity of the mono are excellent throughout, Perspecta is undeniably bigger, wider, and more engaging, whereas the restrained 5.1 remix offers a bit of appreciable separation and resonance. The events are set to Bebe and Louis Barron’s entirely electronic score, revolutionary (and controversial) at the time, and honestly, I found it difficult to distinguish between the “music” and the sound effects.

The sole bonus on the movie disc is a new historian commentary track, and the second platter is an extras only HD Blu-ray. The complex, fascinating Robby the Robot so captivated moviegoers that he returned for The Invisible Boy (1957), as well as an episode of the Thin Man TV series, both included here. There are also archival featurettes, promotional clips, more than ten minutes of deleted scenes, outtakes and test footage, a new appreciation of the Barrons’ contribution, plus a broad hour long TCM documentary from 2005 about the genre in the ’50s, much of this content in SD quality. The screenplay is also supplied as a series of still frames for us to flip through. The discs arrive in a slim, slipcased package with reversible cover art, a two sided poster, and a 40 page booklet.

A welcome addition to any science fiction movie library, Arrow’s limited edition restores MGM’s midcentury milestone to its widescreen glory, delivering video and audio that honor the film’s enduring legacy. Its influence extended well beyond Hollywood, even inspiring Dan D’Agostino to name one of America’s most iconic high end audio brands after the technologically advanced Krell civilization. Seventy years later, Forbidden Planet still has plenty of power left in the machine.
