‘Time Bandits’ was before, so it's the other way around.
Besides, you might be unfamiliar with the fact that Gilliam referred to ‘Bandits’, ‘Brazil’ and ‘Munchausen’ as a trilogy about the same thing. Which trilogy evidently ended up having at least nine films in it, excepting ‘F&L’ and me having not watched ‘Quixote’ yet (the latter's theme obviously follows the rest, though).
As for a full-on remake: that's ‘Zero Theorem’. I can only guess that Gilliam lost hope in the subtler approach, and wanted to have at least something new that would get out of ‘Brazil’'s shadow. Which didn't work at all.
