A new clip from Terry Gilliam's The Zero Theorem has been released, Digital Spy said.

Unveiled exclusively through Digital Spy, the preview sees Christoph Waltz's character Qohen Leth chatting with a computerised therapist named Dr Shrink Rom - played by Tilda Swinton.

Computer genius Qohen struggles to name things that bring him joy, while Swinton's character pushes him to elaborate on his feelings.

The movie centres around Qohen as he is hired to discover the meaning of existence (or lack thereof), but his work becomes more confused when he falls in love.

David Thewlis, Matt Damon, Mélanie Thierry and Ben Whishaw are also among the supporting cast.

The movie is Gilliam's first since 2009 fantasy The Imaginarium of Doctor Parnassus.
