Empire states that Terry Gilliam and Mr Waltz met backstage at the BAFTA’s one year and promised each other that they’d work together.
Terry Gilliam about Mr Waltz’s performance:
“He’s been brilliant. Christoph will come up with an idea on how to do something completely different, That’s why I wanted to work with him – I often just go for the cheap gag, but he wisely resists it. I trust his judgement, in a way, more than mine, because Qohen is never not on screen. You’ve got to find him interesting so you’re not bored of a man in his egocentric despair”
