A very successful film,
Brief Encounter (1945), had been made from
Still Life, one of the plays that made up
Tonight at 8:30. In July 1948,
Sydney Box, head of
Gainsborough Studios, paid £10,000 to
Noël Coward to script
Astonished Heart from
Tonight at 8:30. Box also planned to make a film called
Tonight at 8:30 consisting of
Fumed Oak with
Kathleen Harrison and Jack Warner,
Family Album with Margaret Leighton and Graham Payn, and
Red Peppers with Cicely Courtneidge and Jack Hulbert (This film would become
Meet Me Tonight with a different cast.) Box was happy with the script for
Astonished Heart and put it into production with
Michael Redgrave in the lead, with Coward's approval. Redgrave wrote in his memoirs that Coward called him personally to offer him the part, saying only he or Redgrave could play the part. Redgrave wrote that the script - which he said was by
Muriel Box although only Coward is credited - was faithful to the play, although the actor struggled with how his character committed suicide. Rehearsals took place at Denham, during which Redgrave says he began to lose confidence. He wanted to alter some of the words, but Coward's contract forbade that. Filming started in June 1949. Coward had been away in Jamaica and the US, arriving back in London on 13 June. The next day, he went to Pinewood and wrote in his diary "Saw rushes and rough cut. Margaret Leighton and Celia absolutely brilliant, but Mike [Redgrave] definitely not right. Had a talk with him and then, on the way home, decided to play the picture myself. The situation now is tricky." The following day, he met with Tony Darnbough, Sydney Box and Redgrave. Coward wrote "It was mostly a duologue between Mike and me. Eventually he suggested that I play the picture myself. He behaved really and truly superbly, and I will always respect him for it." It was the first time Coward would appear in a film since
In Which We Serve in 1942. Redgrave later said he suggested other actors, including
Stewart Granger before Coward's name was mentioned. He reflected "that Noél himself had probably engineered this situation as the most tactful way of replacing me." Representatives of J. Arthur Rank tried to get Coward to appear in the film for nothing but he refused. He was given a guaranteed £25,000 and a percentage of the profits. Another source says Coward was paid a fee of £15,000. Filming took place through June and finished on 19 September. On 1 September, Coward wrote in his diary "it is obviously going to be a fine picture." On 10 November, he saw a rough cut while working with composer Muir Matheson. Coward wrote, "There is an essential lack in the picture, and that is that I am never seen being a great psychiatrist and the reasons for my suicide do not seem enough. It is nearly good but not quite." ==Critical reception==
