The full two-hour production was broadcast on PBS, Watertown, N.Y. on 2007 March 25 without commercials.Intriguing plot. It took a while for me to realize that that the genre was supernatural, requiring some suspension of belief. Gradual subversion of most of the crew by the spirit of the submarine was well done. What was not made clearly enough in the movie is that the submarine went through a time-warp... twice; the first time, gradually back into the WW II period and the second time, rapidly, when the submarine encountered the peculiar electrical storm. Time-warp explains the attack by WW II vintage Me 109 aircraft mid-way through the movie and the sudden re-emergence of the sub back to 1981 for the final attack on the, by then, Soviet naval base. It also explains why the sub could sink enemy (German) vessels, including another submarine, without triggering WW III.I'm not sure about British subs but US subs certainly had radar later in WW II. Unfortunately, the movie sub lacked a radar antennae. A minor quibble.Yes, subs did sink other subs, usually when one of them was on the surface. However, the last German sub sunk by combat in WW II was by a British sub whilst both were under water. The British captain was a master at tactics and working out fire control coordinates. (The last German sub to be sunk in WW II was by HMCS New Glascow, a frigate, which was unaware of the sub and accidentally rammed it whilst the latter was partly submerged and trying to sneak to its home port.)Incongruities:As pointed out by others, chlorine gas is produced by sea water entering batteries, not by shorting them out. Shorting out the batteries would have caused failure of the electric propulsion and the sub could not have run under water. Okay, maybe only some of the batteries were shorted out.WW II torpedoes had safety devices to prevent them becoming armed or the torpedo engine starting whilst they were still in the torpedo tube.How was it that the captain and the professor could continue inside the sub without gas masks after the crew had been forced to abandon it because of chlorine gas?Worse, at one point, after all the crew except the captain has abandoned the sub, the professor re-enters the submarine via the conning tower, whilst the sub is submerging, in order to fire the scuttling charges (explosive charges intended to deliberately sink the submarine in order to avoid capture by the enemy). All he had to do to sink the sub was to leave the conning tower hatch open as the submarine submerged.With a little thought and expert advice the producers could have avoided or glossed over these incongruities. As it was, incongruities in the second half of the movie spoiled the mood that was well established in the first half of the movie.

Very average, and predictable.Some good moments though, but was let down by cheap and nasty CGI FX.This was, however a decent TV short drama which can was good to watch once. Doesn't quite have the longevity to persuade me to purchase the DVD to build my collection.This certainly won't be one of David Jason's more memorable roles as it doesn't have the charm and complexity of shows such as Open All Hours and Only Fools and Horses.As usual with ITV Dramas, the constant interruption of commercial breaks added to my disappointment of this programme. Although at some points my attention was drawn to the show, the frequent commercials were very off-putting and the temptation to switch over to an alternative channel was high.

I don't tend to watch a lot of television (preferring to stick to DVDs) so something has really got to interest me to get me to firstly remember the programme's on and secondly to actually watch.The thing that immediately attracted me to the programme was, of course, fabulous actor David Jason. And yet again he excels himself in this wonderful thriller.The story is based on a book also called 'Ghostboat' and is about a submarine called the Scorpion that surfaces in 1981-but which hasn't been seen since the second world war where it was presumed to have sunk. When it sank only one survivor was found, Jack Hardy (David Jason) who can't remember anything due to amnesia) When the sub resurfaces, Hardy is invited to go on a journey on the sub, with another crew and retrace the path the Scorpion took to find out what happened to it.When they first go onto the sub to check out the damage and pull out the bodies of the dead, they find something astonishing. There are no bodies, everything is as the crew left it 40 years ago, nothing has changed.And so the journey begins. Hardy can hear voices, things are happening in the same way they did 40 years ago-and the crew are beginning to change. As Hardy says 'The past is breaking through' The CGI effects in the film are very, very good, although not perfect, the storyline is gripping, the acting and cast are stellar.The perfect thing for the family to gather in front of the telly to watch-10/10!

David Jason is brilliant. Sadly a good actor cannot salvage an obvious story line (which owes a lot to other works, such as the similarly named Ghostship) which meant it all became a little predictable, and towards the end just plain silly.Characters behave inconsistently and illogically as the story lurches towards the less than surprising end.The special effects themselves were also erratic - obviously a lot of money was spent on the set of the sub, but the cgi shots ranged from the okay to dreadful.Okay if you are bored, but not the great work I was expecting.
