Tune In Tuesday: Hammer's "Four Sided Triangle" – A Sci-Fi Obscurity Reborn

Alright,

it’s time to dust off those late-night UHF vibes and dive into a deep-cut from Hammer Films that isn’t about capes, fangs, or Cushing with a crucifix. Four Sided Triangle (1953) is one of those eerie, cerebral sci-fi flicks that snuck under the radar but deserves a spot on your cult-classic shelf. Thanks to this fresh Blu-ray release, it finally gets a chance to shine beyond grainy TV re-runs and bootleg VHS copies.

The Film

If you ever wondered what would happen if Frankenstein had more of a Twilight Zone moral dilemma, this flick has you covered. Directed by Terence Fisher—yes, the same guy who would later redefine Gothic horror for Hammer—this one leans into heady sci-fi with a tragic love story at its core. The plot? Two scientist pals, Bill and Robin, both love Lena, but she only has eyes for Robin. So, what’s a lovesick mad scientist to do? Clone her, of course! The result? A mess of existential dread, ethical quandaries, and some delightfully vintage lab equipment that wouldn’t look out of place in a Doctor Who serial.

The Blu-ray

This edition is a dream for those of us who appreciate boutique restorations of forgotten genre gems. The slipcase art alone is worth displaying, rocking a retro-futuristic vibe that feels straight out of an old-school sci-fi pulp mag. But what about the actual transfer?

Video Quality: Hammer aficionados will appreciate the crisp black-and-white restoration. The moody shadows and lab-set lighting pop like never before, making this feel like a proper early ‘50s sci-fi noir. No more murky TV prints—this is the cleanest it’s ever looked.

Audio: The mono track keeps things faithful, crackling with that vintage charm while being clean enough to catch every dramatic pause and ominous line delivery.

Extras: If you’re into deep dives, there’s some solid supplemental material. Expect commentary, archival interviews, and a peek into Hammer’s pre-Dracula sci-fi output.

Final Verdict

If your movie nights already include classics like The Quatermass Xperiment, Donovan’s Brain, or The Man Who Changed His Mind, Four Sided Triangle will slide right into the mix. It’s not the pulpy monster-mash Hammer is known for, but it’s a fascinating entry in their catalogue that deserves more love. And with this Blu-ray, it finally gets its due.

So, grab your favorite neon-lit snack, dim the lights, and let this relic of 1950s scientific hubris pull you into its twisted world. Because on Tune In Tuesday, we celebrate the weird, the lost, and the wonderfully obscure
