CANNES, France (AP) — Francis Ford Coppola on Thursday will premiere at the Cannes Film Festival a film on which he has risked everything, one that’s arriving clouded by rumors of production turmoil. Sound familiar?

On Thursday, Coppola’s self-financed opus “Megalopolis” will make its much-awaited premiere. Other films are debuting in Cannes with more fanfare and hype, but none has quite the curiosity of “Megalopolis,” the first film by the 85-year-old filmmaker in 13 years. Coppola put $120 million of his own money into it.

Forty-five years ago, something very similar played out when Coppola was toiling over the edit for “Apocalypse Now.” The movie’s infamous Philippines production, which would be documented by Coppola’s late wife, Eleanor, was already legend. The originally planned release in December 1977 had come and gone. Coppola had, himself, poured some $16 million into the $31 million budget for his Vietnam-set telling of Joseph Conrad’s “Heart of Darkness.”
