Now, the documentary maker and all national treasure, 50, has revealed one titbit of behind-the-scenes gossip he acquired when he starred on The Great British Bake Off in honour of Stand Up To Cancer earlier this year.
And this new piece of news will change how you see the show forever,
Louis revealed that hosts Noel Fielding and Matt Lucas actually film the time announcements sporadically around the day and not during the challenges themselves - which would be a huge distraction to the bakers if they were to do it live.
"The secret I'm going to tell you is that when they say 'Bakers, you have 15 minutes left.' They do those irrespective of the time. They get them as a shot," he told Cosmopolitan.
"They basically say to you, 'Just ignore that - we need that shot.'"
The most recent series of The Great British Bake Off, which wrapped last month, was won by 20-year-old student Peter Sawkins, who currently stands as the youngest winner of the programme so far.
Speaking about his success, he explained: "I can't quite believe that I'm here. This is gonna be a really huge chapter in my life, and what a way for it to end."
This year's edition of Bake Off was particularly special, as it was filmed back-to-back in a Covid-secure bubble in a bid to prevent the spread of coronavirus.
This allowed the contestants to hug and touch without having to abide by the usual social distancing measures.
Contestants had to stay in isolation together and practise their bakes behind the scenes.
It also marked the first series Matt Lucas took over from Sandi Toksvig as presenter, as Sandi chose to leave following three years fronting the show.
