Benny Hill appeared all over the spectrum in his early career though, hopping between the BBC, ATV and the film industry. It was when he took his Benny Hill Show to Thames that he hit the big time. Central Television even offered him a new contract in 1992. Unfortunately he was already dead when it arrived in the post.
Yes, although Central still did the shows anyway, they just did a quick rewrite and Freddie Starr did them. Benny Hill's move to Thames was a highly succesful one for him, he got huge ratings and made loads of money - it all went a bit wrong at the end but for fifteen years or so it worked brilliantly. Everyone talks about Morecambe and Wise but the most hopeless defection is surely Mike Yarwood's move to 1982, which is inexplicable as after Eric and Ern had left the Beeb he was by some distance their biggest star, and his career was already on the wane when Thames signed him.
Just to correct was was said earlier, it wasn't Ernest Maxim who stayed at the Beeb when Morecambe and Wise moved, it was Eddie Braben. Maxim was their producer. In fact Braben followed them not long after, and their first Beeb producer John Ammonds came back at Thames as well. There were other factors why Eric and Ern flopped on ITV - after two shows in 1978, in October and on Christmas Day, Eric had a heart attack and then there was the ITV strike, so they couldn't actually do a show for ages, and the only thing they did in 1979 was an interview with David Frost - which was still shown on Christmas Day because they were so desperate to get them on there.
As was said, their Christmas Day shows only stopped because Christmas was at the weekend in 1981-83. In those years the Christmas show was on Wednesday 23rd, Monday 27th and Boxing Day respectively, but you can be sure that, if they had been weekdays, Thames would have shown it on Christmas Day. They put the Morecambe tribute on Christmas Day in 1984 and showed a million repeats, as well as giving Ernie a load of work afterwards. Thames were still really committed to them, although the viewers had gone off them a bit.
