John Challis, best known as Boycie in Only Fools and Horses, has called Roger Lloyd Pack "remarkable" and "irreplaceable":
I spoke to Roger two days ago.
Roger said it was a bit awkward to talk at that particular moment. It is very sad and very distressing.
My thoughts are with his family. He was a remarkable man and he'll be missed.
Roger is irreplaceable. It's a very sorry day.
