The 1957 film of Agatha Christie’s play Witness for the Prosecution is a delightful, captivating, well-constructed affair. As long as you don’t figure out the key twist (which relies on a very skillful act of legerdemain), it will bowl you over. And even if you do figure it out – as I did – Christie still throws in one or five shocks at the end for good measure. Impeccably acted by Charles Laughton, Elsa Lanchester and Tyrone Power (and with a debatable performance from Marlene Dietrich thrown in for good measure), it’s a bona fide success. So, how does the 1982 TV remake stand up?
