Sex with a Smile
Sex with a Smile is a 1976 Italian comedy film starring Marty Feldman, Barbara Bouchet, Edwige Fenech, Dayle Haddon and directed by Sergio Martino. While the cast was relatively popular internationally, advertising for the film in the U.S. concentrated almost exclusively on Marty Feldman, even though he only appeared in one segment of the film.
The original Italian title was 40 gradi all'ombra del lenzuolo, colloquially translatable as 104 Degrees Under the Sheets (40 degrees Celsius equals 104 degrees Fahrenheit). It was followed by a sequel entitled Spogliamoci così senza pudor, colloquially translatable as Let's Get This Naked without Modesty.
