I scarcely ever like biopics, and as it turned out I wasn't going to start with "Churchill's Secret". The main reason is that they nearly always take a lend of a famous personality to provide audience motivation and engagement, rather than relying on the merits of the story and the screenplay. The Churchill legend is tapped here and it turns out to be a weak basis for a rather dull and slow movie. In some ways I didn't mind spending a couple of hours in this world, mainly because of the Chartwell setting which brought recollections of a past visit. The character actors do well with what material they have, and are well-costumed and coiffed. I think it's a weakness that the film focuses on family drama rather than evoking national and global tensions, which are referred to, but not effectively exploited. Lindsay Duncan is beautiful to look at as Clemmie, but she is rather unlikeable, which is a pity. Michael Gambon ticks a familiar box as a senior British male actor in portraying Churchill, but his depiction didn't especially evoke Churchill for me. It's a tough call, but it's one of the weaknesses making this film an "also ran".
