For the second time, Monty Python member Terry Gilliam is working on a movie about the meaning of life. The Zero Theorem stars Christoph Waltz as angst-ridden and essentially hairless computer genius Qohen, working on the titular zero theorem. That theorem is centered on an equation that is supposed to prove existence is entirely meaningless, but as Qohen meets "the girl with pink hair" — played by Mélanie Thierry — he starts to understand both the "power of love and desire," and his own reason for existence.
