The actor is at the 75th edition of the prestigious festival to premiere two sweeping dramas in which he has complex leading roles. The first is Saela Davis and Anna Rose Holmer’s GOD’S CREATURES, a gripping thriller set on the Irish coast following a mysterious man who is accused of a terrible crime that his devoted mother can’t possibly imagine him committing. The second is Charlotte Wells’s delicate, touching AFTERSUN, in which he’s cast as a divorcé on a summer holiday in Turkey with his young daughter. Both films have been met with rave reviews, particularly for Mescal’s measured, nuanced performances.
