French authors, filmmakers, and actors are outraged. Unlike the Hollywood model, French cinema does not rely on private equity and box-office sales to survive. But aspiring media moguls like Mr. Bolloré, who has been called “the French Rupert Murdoch,” can still reshape the output of French creative industries. For many artists who have protested recently, it is specifically Mr. Bolloré’s ties to the far right that is the concern. Similarly, French cinema risks coming to a standstill if the two sides refuse to cooperate.
