The House Across the Lake (1954 film)

The House Across the Lake is a 1954 British film released in the United States as Heat Wave. The film noir drama, filmed and set in England, stars Alex Nicol and Hillary Brooke, who are the only Americans in the cast. Brooke actually plays a British character, as she did in most films. Her mastery of a posh accent caused her to be typecast as British in Hollywood films starting in the 1940s.
