He has been behind two of ITV's biggest shows, and now the BBC has also turned to Simon Cowell's company to produce a hit stunt for Strictly Come Dancing in the form of a dance show show judged by the public.
The biggest dancer, starting January 5, "transfers power to the people" in a contest that gives the winner £ 50,000 and a guest appearance at Strictly.
In departing from Cowell's previous hit, The X Factor and Britain's Got Talent, where talent experts decide on the winner, at The Great Dancer, studio audiences are judges. If 75% of them vote for an action by turning on a light on their seat, the mirror behind the practitioner blocks himself to show them to the audience.
Also in the audience are three experts – singer Cheryl, Strict professional dancer Oti Mabuse and Glee actor Matthew Morrison – who will train the last nine actions and give them feedback. At points, their frustrations become apparent when they see talented artists overlooked by the audience.
Morrison said: "It is difficult to sit there as a person who has studied dance, but it comes down to the general population's dance. It can be a good thing, and it can also be a bad thing because they do not understand the hours and the engagement and The sacrifice it takes to be a great dancer, but maybe there was something in them that didn't connect.
Nigel Hall, worldwide television in Cowell's Syco Entertainment company, said: "You can't be a showbiz star if people don't want to see you, and often it wasn't the best technical dancers, but the dancers who had the heart and passion and Commitments that received 75% and then opened the mirrors. As Simon often says, you must have the likeability factor! "
Hall, who used to be an executive producer of stars in their eyes, said, "I thought to combine some kind of doors that open with the split of a mirror down the middle and make it a reveal, would be something new and unique to dance. "
He said Cowell, who has not worked for the BBC before, had been the "key" to the show of the show, funded by the pilot, helped fine-tune the format with co-producer Thames, and "he told Cheryl that she would be angry to screw it down ".
The greatest dancer will be presented by Alesha Dixon and Diversity dancer Jordan Banjo and have a diverse range of participants.
Strictly still very popular, but is now 15, so the BBC is eager to find more new Saturday night shows.
The BBC's Content Director, Charlotte Moore, described the Greatest Dancer as "epic, warm and very much a people's show. We are very happy about it."
Asked about how to be a mentor at The Great Dancer compared to being a judge on the X Factor, Cheryl said it was different: "It felt more competitive with the X Factor because someone eventually won a massive record deal. With this show .. "You're not trying to create a career, hopefully a platform, but not a career."
Thames CEO Amelia Brown said all kinds of dance actions were welcome, from ballet to street, and "the result is … a dance show with some magic".
