David said: “One of the things I always measure an actor by is the difference between how they are in real life and the parts that they play.
“So it comes as a bit of a surprise sometimes to people that John Challis was such a kind, and such an ordinary, loveable sort of chap.
“[He was] totally different to the character Boycie that he played.
“A lot of people tend to think that was John.
“But it wasn’t. That was him just [showing] the skill that he had as an actor to portray Boycie the way thay he did.
“Because it was totally against his natural nature.”

The Only Fools, Open All Hours and A Touch Of Frost star then went on to express his shock at how quickly the disease took his friend.
“It wasn’t a complete surprise, because poor old John hadn’t been well for the last month or two,” he said.
“He went downhill so fast, very rapidly.
“One minute we were thinking he was on the road to recovery, and then sadly it took him quite quickly.
“We’re still suffering a bit of shock, I’m afraid.”

Yesterday, tributes poured in for John, who was recognised as one of the nicest men in show business.
Playing shady used car salesman Boycie since the legendary sitcom began in 1981, John was loved by millions.
Sue Holderness, who played John’s onscreen wife Marlene in the show, paid her own tribute.
“Marlene without Boycie – it’s unthinkable,” she said on Twitter.
“John Challis was my partner on screen and stage for 36 years and my beloved friend. R.I.P. darling John. I will miss you every day.”
