Not a bad effort. Good central performance by Donald Pleasance which, by all accounts, captured the nature of the man. Set during the trial with the actual events told in flashback.
Coral Browne is his doomed wife and Samantha Eggar plays his mistress Ethel Le Neve. Photography throughout is unremarkable apart from a beautiful shot of Ms Eggar, all in black, turning and walking away from camera whilst the end credits roll. Director of Photography was a certain Nic Roeg.
