Sunburn

Lumpy-but-loveable Charles Grodin is the insurance investigator, sniffing out a swindle among Acapulco's lotus-eaters; Fawcett-Majors (comely but coy) is posing as his wife, while emphasising that a quick bunk-up is out of the question. Together they're in a routine comedy-thriller, which looks good but is neither funny nor thrilling, and carelessly wastes its supporting cast, with Art Carney reduced to caricature and Joan Collins on automatic pilot in a hilarious replay of her rich-bitch nympho persona.
