Bill Goode Spoiler Alert - Ending Revealed This film is full of suspense, but has several points that are very unrealistic.1) It is very unrealistic that any drug would have a beneficial reaction to another toxin. It makes an interesting plot, but it's a very unrealistic scenario. Equavil, the fictional drug in question, is described to treat "reactive depression". Therefore the presumed effect it would have would be to increase anxiety, the reaction that the crew was already having to the toxin in the paint. That makes the story of Equavil neutralizing the toxin totally implausible.2) The crew exited the submarine Montana North of the Arctic Circle, possibly even North of 70 degrees latitude. The water temperature at that latitude would be unbearably cold. The crew would not survive long enough for more helicopters to get to them, except those in the rafts. But as can be viewed in the film, most of the crew were not in rafts, but in the water.3) What was the purpose of Capt. Allard Renslow jumping out of the helicopter into the water? He could not possibly help any of the crew in the water, once he was in the water himself, especially water as cold as it would be North of the Arctic Circle. Renslow jumping into the water had a dramatic effect to rejoin with Van Meer. Nevertheless, there was no way Renslow would be any benefit to Van Meer or any of the other crew in the water.

ddc300 When I first saw this years ago on network TV, I knew the story seemed familiar, but I couldn't remember where I saw it. Then "Voyage to the Bottom of the Sea" was released on DVD and it came to me: there was an episode where a 'sister' submarine was destroyed and the Seaview was sent to investigate. Along the way the Admiral (Richard Basehart) becomes an unstable paranoid -- much like David Soul in "Fifth Missile". I forgot the specifics, but as with this movie the plot device of 'something in the air' is used to create a tense situation on the submarine.Good performances from a solid cast of pros makes this an interesting TV movie. Had there been a larger budget this could have made an excellent theatrical film. Some obviously poor special effects and a dull soundtrack are overlooked because the plot's tension keeps things moving.This film is ripe for DVD distribution.

Julia LaFontaine Yes, it is a bit cheesy. But it's suspenseful and entertaining, and one of my favorites; there are some excellent actors in the film, and they do a commendable job given the limitations of plot and characters. It's interesting to see David Soul in a 'bad guy' role; I thought he was quite believable--and rather chilling--as the ever-more-paranoid CO. Robert Conrad is a long-time favorite--I think he brings his character to life very well; and Sam Waterston has been star quality in everything of his I've watched--movies or TV. I watch this movie every so often but our tape (a VHS TV copy I got) is such poor quality it's difficult to fully enjoy it. This is a movie I think they should put out on DVD; maybe it wouldn't be universally sought after, but I'm sure there are lots of people like me out there who like this sort of film so there WOULD be a market for a DVD version. I'll keep hoping!

swanson7409 It's interesting that someone made a comparison of the "Fifth Missile" to the Star Trek episode. It should be pointed out that the original Star Trek TV episode in which the crew of the Enterprise undergoes a space madness while orbiting planet Si 2000 is entitled "The Naked Time", not the "Naked Now". The "Naked Now" refers to the first regular Star Trek The Next Generation episode in which the Enterprise-D encounters a science vessel. This episode, though, does refer to and is based on the "Naked Time" original series one.Now, to the Firth Missile. While the reactions of the crew in the Star Trek episodes were based on those similar to alcohol intoxication, the crew's condition on board the Montana was caused by a much more serious situation, namely the paint vapors emitted by the faulty bulkhead finish. There are few places where such a reaction could have more serious consequences than among a crew who has responsibilities as serious as a crew on a ballistic missile submarine, and of course this is what makes the film so suspenseful and such a thriller. The plot is very believable. At the same time, this film, along with "Crimson Tide", "The Day After", "By Dawn's Early Light", "The Hunt For Red October", "Ice Station Zebra", and many other similar movies give us much insight into how easily things could go wrong and just how easy it could be for a nuclear holocaust to begin. Thankfully such an event has not occurred and (God willing) such an event will not happen.
