During filming of the finale, Peter Capaldi dislocated his thumb during an ‘overenthusiastic’ take (according to actress ’Maime McCoy’. She said “…his thumb had completely dislocated - he’d quite instinctively just slipped it back in - and then the colour went from his face.”
Capaldi said the shooting of the sword-wielding adventure series was beset by injuries: “Dislocated shoulders, bruised shins, the odd concussion. It’s one of the occupational hazards of being a swashbuckler.
"I myself suffered a nasty dislocated thumb, but embarrassingly not from swinging a sword around. Instead, my injury came from a domestic the cardinal was having with milady, Maimie McCoy.
"I threw her against the wall not realising I’d caught my thumb in her large frock. I felt a jab of pain. And when the director said 'cut’ I looked down and saw my thumb was on the wrong way round. Nasty. Instinct took over and I shoved it back - which made my eyes water and my knees weak.”
He added: “The lesson clearly was, never get into a fight with Maimie McCoy.”
