The 75th Cannes Film Festival has opened, with more than 100 films being shown in the official selection. The event is good news for the local economy and an essential stop for many in the entertainment world. For Daniela Elstner, the executive director of Unifrance, an organisation that promotes French cinema worldwide, Cannes can be a "gamechanger" for filmmakers. She explains that "the destiny of hundreds of films is negotiated at the festival". Also in the programme, we look at whether streaming platforms such as Netflix have reached their peak.
