Up to His Neck is a 1954 British comedy film directed by John Paddy Carstairs, starring Ronald Shiner, Hattie Jacques and Anthony Newley.
[2][3][4] Sailor Jack Carter has been marooned for ten years on a South Seas island, and treated as a King by natives.
He is eventually rescued by the Royal Navy, who then use him to train up commandos to recover a stolen submarine, and to foil an oriental criminal plot.
The Monthly Film Bulletin wrote: "This farce, reminiscent of the pre-war George Formby comedies, seems to have learnt nothing during the intervening years.
Ronald Shiner shouts his way through it all with high spirits and works hard with a script almost devoid of funny lines.
