While Francis Ford Coppola's Megalopolis may have captured much of the attention at this year's Cannes Film Festival, another self-financed passion project by an old-school Hollywood filmmaker made its debut on the Croisette to a much more muted response. Kevin Costner's Horizon: An American Saga - Chapter 1 is the first part of planned series of four films, one of which, Chapter 2, has already been shot and was planned for release in August before it was unceremoniously delayed due to Chapter 1's underwhelming performance at the box office.
