Jóhann Jóhannsson (best known for his melancholy "Prisoners" score) likes simplicity and pattern-based construction. And he's found the perfect artistic expression in "The Theory of Everything," conjuring a musical Big Bang about physics and love that just might earn him the Oscar. "The thing about this film is that it's intimate and very small in many ways, set in these town houses and corridors and classrooms, but it's still very cosmic and has an epic quality as well, which is an interesting balance," explains the Icelandic composer who's next score is for "Prisoners" director Denis Villeneuve's "Sicario." And that was fun to deal with because it has such a wide scope.
