"I'm happiest on set because I'm not myself. I'm someone else. The moustache, the dinner jacket. It's not me. You're always this sort of double, and it's liberating. Imagine being stuck with yourself... all those doubts"

In this quote, Jean Dujardin expresses his love for being on set and playing various characters. He discusses that when he is on set, he is able to leave from his own identity and become somebody else. The physical improvement, such as wearing a moustache and a dinner jacket, allows him to fully immerse himself in the function and leave behind any doubts or insecurities he may have about himself. Dujardin sees this as a liberating experience, as he is not restricted to his own constraints and can explore different elements of his personality through his characters. He contrasts this with the concept of being stuck to oneself, which he views as a complicated and limiting prospect. In general, Dujardin highlights the delight and liberty that comes with having the ability to enter somebody else's shoes on set.
