A group of young Londoners decide to fake a Loch Ness Monster sighting to boost book sales.

Lightweight fluff featuring a gallery of British comedy players with several sporting dodgy Scottish accents.

A few genuine Loch Ness location shots are jarring cut with bits of business filmed at what looks suspiciously like Frensham Ponds replete with a different set of extras.

7 year old me did like the 'twist' ending though.

I can find no evidence thus far that this film opened in the US, although there are articles about Adam Faith's participation.
