Adam Faith is not a bad actor, and so I gave this a look, but he was wooden in this, and the whole thing made for an absolute load of rubbish. Didn't even make me smile.
Sid James, Freddie Frinton, Charles Hawtrey, Wilfrid Brambell, Spike Milligan (briefly), Clive Dunn, Terry Scott, Gordon Rollings etc. etc. and the gorgeous Carole Lesley, who sadly committed suicide aged 38 when the studio cancelled her contract.
As somebody on the IMDb put it :-
Sadly, despite a whole host of reliable British comedy actors in the cast list and some well-known names behind the scenes (Terry Nation and John Barry) this is a pretty dreadful movie.
Four hip kids need money and so decide to mock a Loch Ness monster, take photographs in London's Serpentine, then drive up to Scotland and Loch Ness in a Rolls Royce hearse, to make a killing on the photograph. I mean, the very idea is just awful.
I think Adam Faith released a record of the title, which may have been more successful than this pile of doo doo.
