French stars are rightly worried by billionaire Vincent Bolloré. Here’s how to rein him in

The conservative tycoon’s grip on media and cinema is unhealthy. An EU fund could protect democracy in perpetuity

The shadow of Joseph McCarthy’s “red scare” loomed over the storied steps of this year’s Cannes film festival. Echoing the mid-20th-century blacklist, which shut out about 300 suspected communists from Hollywood, the French media group Canal+ announced an effective ban on twice that many French cinema professionals, including actors such as Juliette Binoche and film directors such as Jean-Pascal Zadi and Arthur Harari. Their crime? An open letter denouncing the growing influence on French media and cinema of conservative tycoon Vincent Bolloré, Canal+’s main shareholder.

The Canal+ chief executive, Maxime Saada, justified punishing the signatories on the basis that their claim was an “injustice” against the staff of Canal+ – who were, he said, committed to the organisation’s independence.
