Great Film! Best by director Yeaworth, Great FX, Great job by Lansing!

Loved this when I first saw it in '59. Still love it! Took me a while to dig the jazz score, but now I love that too!

What an original idea. Can't recall anything like it. The rotoscoped FX still give me the creeps, especially with that eerie music, like fingers circling the tops of wet glasses.

This was Robert Lansing's first theatrical lead and he does a spectacular job, from dry, low-key lab rat to wounded-by-love to power-obsessed fiend. He's multi-dimensional, a classic movie monster on a par with the greats from '30s & '40s Universal (Karloff, Lugosi, Chaney, Price). It's a grand performance that builds to a chilling climax.

Congdon & Meriwether are fine as lovers. Supporting cast make great victims.

This is the second of director Yeaworth's three back-to-back sci-fis: The Blob (1958), 4D Man (1959) & Dinosaurus! (1960). All had unique, memorable plots & FX. The Blob was the best jelly-beast ever made, with Steve McQueen & a great theme song by Burt Bacharach. Dinosaurus, the weakest of the three, at least tried to do stop-motion, even though it's crude.

But 4D Man is -- by far -- Yeaworth's best. Unlike The Blob & Dinosaurus, there's no silly juve nonsense. Patty Duke, 4D Man's kid, is sharp. Not cutesy & annoying, like kids in the other two. 4D Man is all adult, with believable, nuanced male-female relationships. By far the best script Yeaworth had.

This is old-school, classic movie horror. Low budget, but still great!
