Though you might have missed The Zero Theorem and its colorful sci-fi wonders in theaters (it was this author’s #1 film of 2014), it comes to Blu-ray and DVD January 20th from Well Go USA Entertainment and is very much the multi-layered, ingenious head trip you would expect from director Terry Gilliam (Brazil, 12 Monkeys). We have an exclusive behind-the-scenes clip that shows the method in the madness, which you can check out below!

In the clip, Gilliam talks about how he would not have been able to make the film without star Christoph Waltz, who plays introverted computer jockey Qohen Leth. The director tried for years to get the film off the ground–at one point with Billy Bob Thornton in the role–but could only pull it off once the two-time Oscar-winner (Inglourious Basterds, Django Unchained) signed on.

Featuring a screenplay by Pat Rushin, The Zero Theorem co-stars Mélanie Thierry, David Thewlis, Lucas Hedges, Tilda Swinton, Ben Whishaw and Matt Damon, and revolves around an eccentric and reclusive computer genius plagued with existential angst who works on a mysterious project aimed at discovering the purpose of existence ­or the lack thereof­ once and for all. However, it is only once he experiences the power of love and desire that he is able to understand his very reason for being.
