'Our Mutual Friend' tops my list!
Then 'Persuasion' (Ciaran Hinds), 'Pride & Predjudice' (Colin Firth) & 'The Forsyte Saga' (Damian Lewis).
There've been just so many over the years & they're soooo good, they can withstand endless viewings.
EVERYTHING about them is just superlative! But it's the 'acting' that's the big drawcard for me!
