The film was entered into the Cannes Film Festival in May 1981. It had a total of 1,197,816 admissions in France, with Blier claiming the poster chosen by the distributor was awkward and discouraged the public from seeing the film. Besse's parents sued the distributors and producers over the poster, which shows Besse's breasts, as it was placed on billboards around France without their permission. The judge favoured the producers, saying the film was more revealing than the poster. "Beau Pere" was among Blier's least commercially successful films.
