Available again on DVD, to coincide with the film's 50th anniversary, this is a top quality movie. The acting, screenplay and black-and-white cinematography are first class, with an astonishing Oscar-winning performance by Simone Signoret, as the older, unhappily married woman who falls for social climber Laurence Harvey, with tragic consequences.
Trivia : Signoret was the first French lady to win the Best Actress Academy Award since Claudette Colbert (1934 - It Happened One Night).
Hermione Baddeley's two minute cameo is the smallest role ever to bag an Academy Award nomination (Best Supporting Actress). Room At The Top [1959
