The premise of "Fantastic Voyage" seemed very unlikely in 1966, however in 2002 I'm not so sure.

The story concerns a top secret miniaturization program being developed by the Americans and concurrently by "the other side". A scientist from the other side has the secret of counteracting the situation where the miniaturization effects wear off after one hour. Unfortunately, the scientist receives a brain injury in an assassination attempt. This results in General Carter (Edmond O'Brien), the commanding officer of the project deciding to "send in" a team of experts miniaturized, to the injured man's brain to repair the damage.

The team consists of Drs. Duval (Arthur Kennedy) and Michaels (Donald Pleasance), Pilot Capt. Owens (William Redfield) and the romantic leads, Grant (Stephen Boyd) and the ever lovely Raquel Welch as Duval's assistant. Assisting O'Brien as a medical expert is Arthur O'Connell as Col. Reid. Of course, as in most film's of this type there is the inevitable fifth columnist aboard. The acting is good, particluarly the performances of veterans Kennedy, Pleasance, O'Brien and O'Connell.

The real star of the "Fantastic Voyage" are its amazing special effects. Filmed long before today's computerized digital effects, this film still makes believable, the illusion of a team of people being injected into a person's bloodstream. To fully appreciate the effects the viewer should see it in its widescreen format.
