A low budget British film set entirely on Hampstead Heath during one summer afternoon. Don't be misled by the title, the film is more about relationships than sex. The film focuses on a number of couples on the Heath - including an elderly couple meeting again after 50 years, a recently divorced couple, a gay couple, a couple on a blind date and a horny young man desperate to couple with anyone (or anything). The script is absolutely spot on and full of touches that will make you smile broadly if not laugh out loud. Quality acting by a number of Englsh actors - Benjamin Withrow and Eileen Atkins as the elderly couple, Ewan McGregor as a manipulative gay man, Mark Strong as an enigmatic wealthy indivdual, Tom Hardy as the horny young man and particularly Hugh Bonneville and Gina McKee on an excruciating blind date stand out.
