Another classic of Screen monsters, ''The Fly'', involves Man vs Science (with horrifying result). Made in 1958 (in color), our Scientist is trying to perfect molecular teleportation (ala Star Trek). Creating a machine that breaks downs a subjects into sub-atomic particles, these are them sent at the speed of light (it's Science-Fiction, of course), the molecules are then reassembled into their original form and shape. After a successful test of first an inanimate object and then a small lifeform, he is ready to try it on himself! Unknown to him, a small housefly is trapped inside the teleportation chamber with him. Upon being resembled, (to his and the audiences horror), his atoms have merged with some portions of the fly (and visa versa). He now had the enormous head and forearm of a fly (while the fly takes his arm and head). Slowly reverting to the fly's instincts, he was find the fly with his components and try to re-merge them. Unfortunately, he is unable to locate the bug, and has his wife assist him in crushing his head and arm in a mechanical press (to destroy all evidence of the experiment. Later, the Scientist's young Son find a small fly trapped in a spider's web (soon to be eaten by a hungry spider. The small human head screams in a tiny voice ''Help Me!'' The boy's Uncle (nearby) see's the horrible truth -  and quickly crushes the fly (and poor spider!). The movie was a cult classic that was eventually remade into several movies and sequels.
