Actor Mathieu Quesnel was more embarrassed to perform his nude scene in this movie than he was in Le Règne de la beauté (2014), since he was with other men in a group shower scene on Le Règne, while he was the only naked actor in his scene in Le vrai du faux.
During the early stages or production, Dan Akroyd was in talks to star in an English language version of this film.
Stephane Rousseau was cast by Emile Goudreault to appease the producers so that he could cast the actors he wanted for the rest of the roles.
The author of the original play was unhappy with the marketing of the film, since they presented it as a straight comedy, which it is not.
