Leslie Halliwell said: "Extended absurdity uncharacteristic of its director."
The Radio Times Guide to Films gave the film 2/5 stars, writing: "Both Amanda Donohoe and Oliver Reed cope well with their roles as the castaway and the sex-mad, middle-aged man who is her companion, but in the end you can't help feeling the nudity is only there to spice up a tale of two selfish people who probably deserved each other."
Variety wrote: "Newcomer Amanda Donohoe spends most of the pic displaying the absence of bikini marks on her body (palm trees always seem to obscure the vital parts of Oliver Reed as Gerald Kingsland), and she copes well with a character whose motives and methods for going to the tiny desert island remain dubious. Reed gives the performance of his career as a sexually frustrated middle-aged man in search of sun and sex, and is admirably complemented by Amanda Donohoe as the determined but fickle object of his lust. Photography is excellent (especially underwater scenes) but though Castaway is a great ad for the tropical Seychelles, it won’t be remembered as a Nicolas Roeg classic." ==References==
