Hard to place

On one hand, this movie is absolutely incredible. The special effects, suspense, and adventuristic elements are very well done and very engaging. In general, it's definitely entertaining and fun to sit back and just allow to take you along, like the ship in the bloodstream. It also throws random thoughts about religion and philosophy out in a way that should at least be appreciated for trying to cater to an intellectual audience, I suppose...

On the other hand, it has terrible dialog, pretty bad acting, one-dimensional characters, is so caught up in the Cold War, and fails to make those philosophical shout-outs mean anything.

Thus, while we're thrown from one aspect of pretty well researched anatomy to another, it can take your breath away two ways: by dazzling with visuals, and by derisive laughter at the total inanity of the writing. It's just too silly to take seriously, and yet it doesn't seem to have been created to be comedic but awe-inspiring.

Modern day audiences, as well, will get a good hearty chuckle at the little Intelligent Design situation. Good to know we haven't gotten any further, really, in our intelligence than when we were scared to death of Russian saboteurs.

Lots of fun and very visual

A group of specialists are miniaturized and, along with a bacteria-sized submarine, are injected into a genius to repair a blood clot in the brain. The premise certainly demands a healthy dose of suspension of disbelief but, once accepted, the result is a colorful, visually amazing spectacle that has enough plot, enough intrigue and tension, enough action, and enough good acting (not a plethora, but enough) to make it a real worthwhile viewing experience. Donald Pleasance was the perfect choice as the team's medical sopecialist, with Stephen Boyd (what ever happened to him?) as the no-nonsense commander, and Raquel Welch is beautiful but brainy.

Shrunk down to small size, they enter the human body.

Mr. Grant (Stepen Boyd) is driven to a secret location. Once there, he is given instructions by General Carter (Edmund O'Brien, DOA [1950]). An important government scientist has a clot inside his brain. The surgery can only be done by sending a samall submarine-line craft inside the human body along with five people. Mr. Grant, Cora (Raquel Welch), Dr. Duval (Arthur Kennedy), Dr. Michaels (Donald Pleasence) and Skipper (William Redfield). They will shrink down to a minute size and medically enter the head. Now inside the human body and traveling through the artery and ther secret passageways, they must get to the man's brain to get the clot. They must not go to the heart. It would be dangerous. But, it looks like they will have too. They also have to find a way to get out of the live body too.
