It’s been a good month for Darren Aronofsky. Just days before “The Whale” won Oscars for Brendan Fraser and his makeup and hairstyling team, Aronofsky’s debut feature “Pi” received an IMAX re-release from A24. Aronofsky oversaw the restoration, which used a technique known as black and white reversal to transfer the film to 8K without losing its trademark graininess.
