Writer/director/producer M. Night Shyamalan returns with an original thriller that delves into the mysterious recesses of one man’s fractured, gifted mind. Though Kevin (James McAvoy) has evidenced 23 personalities to his trusted psychiatrist, Dr. Fletcher (Betty Buckley), there remains one still submerged who is set to materialize and dominate all the others. Compelled to abduct three teenage girls led by the willful, observant Casey (Anya Taylor-Joy, The Witch), Kevin reaches a war for survival among all of those contained within him - as well as everyone around him - as the walls between his compartments shatter apart.
The Split is an authentic, layered and witty exploration of modern marriage and the legacy of divorce through the lens of the Defoes - a family of female lawyers at the heart of London's fast-paced and emotionally-charged divorce circuit.
Esteemed divorce lawyer Hannah (Nicola Walker) quits the family firm when her mother Ruth (Deborah Findlay), formidable personally and professionally, refuses her promotion. Landing at a rival firm alongside old flame Christie (Barry Atsma), Hannah navigates scandalous affairs, big-figure settlements and fraught relationship battles - coming head to head with Ruth and impulsive sister Nina (Annabel Scholey) in the bitter divorce of Goldie (Meera Syal) and multi-millionaire husband Davey (Stephen Tompkinson). Meanwhile, the marriage of younger sister Rose (Fiona Button) looms on the horizon.
When their estranged father returns after 30 years the sisters are forced to confront their past. Facing the reality of her dad's abandonment, and reconnecting with ‘the one who got away' Christie, Hannah begins to question her relationships with the men in her life - including her seemingly contented marriage to the smart and affable Nathan (Stephen Mangan).
