US film director Francis Ford Coppola saluted the crowd with his straw hat as he posed with stars Adam Driver, Nathalie Emmanuel and Grace VanderWaal at the world premiere of his epic film Megalopolis.

Hollywood stars descended on the red carpet of the 77th Cannes Film Festival for the first official screening of the film, which marks a decades-long passion project for The Godfather director Ford Coppola.
