The Unknown review – Léa Seydoux gets invaded in uncanny and bizarre body-swap horror

What happened

According to The Guardian’s source item, The Unknown review – Léa Seydoux gets invaded in uncanny and bizarre body-swap horror, Cannes film festival: A man is terrified to wake up in Seydoux’s body in this metempsychotic mystery film about gender identity Arthur Harari’s film is adapted from a graphic novel he wrote with his brother Lucas called The Case of David Zimmerman. It is a doomy, murky and intriguing supernatural noir mystery, hardly visible within the dark toxic cloud of its own strangeness, populated by people bearing stricken expressions of misery and fear. There are some genuinely uncanny and disquieting moments. Maybe it is a parable for the crisis of gender identity – or just identity, and everyone’s occasional experience of the profound, unreconcilable unknowability of our own bodies. There is also something of the mood of Blow-Up , or Basil Dearden’s Brit pulp chiller The Man Who Haunted Himself , or indeed David Robert Mitchell’s modern classic It Follows . But this one, sadly, is flawed by that
