If you loved The Blob, try 4D Man
A bridge between a film you've already seen and one most people haven't. 4D Man has roughly 10.8× fewer votes than The Blob — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Irvin S. Yeaworth Jr., and they both carry the 3am cult mood tag, and they sit in Horror / Science Fiction territory. If that's the register that drew you to The Blob, the second film will land in a comparable space — through a different lens.
What 4D Man is
Lab basement. Hum. Bare bulb. A new amplifier promises a leap beyond known space. One brother tests it, phasing through walls. Each pass costs him years. To survive, he must steal life from others. Low-budget late-Eisenhower sci-fi provides illicit thrills.
