Why did Guinness never write another screenplay?
What a great script this is.
Especially for a one off which turns out to be the case here. Considering how good it is and how well received it was, I am left to wonder why there weren't more...
Obviously he is a great actor and this is one of his best roles, but The Horse's Mouth is also one of the best examples I've seen of a movie with a lead actor who also wrote the screenplay.
