Nic Cage has long been a mainstay of the Cannes market thanks to his willingness to appear in any film no matter how dreadful. But something went horribly wrong last year: his psychedelic horror flick Mandy was so good that it actually got into the festival’s Director’s Fortnight sidebar. Thankfully he’s back in the basement this year hawking two efforts: a schlocky thriller called Grand Isle and this drug-running drama, also starring Laurence Fishburne. ‘Tastes like heaven, burns like hell,’ growls the tagline, which evokes less a prestige drama and more a nasty STD.
