Matthew Perry docuseries leans on his closest friends, not Friends co-stars

Netflix's three-part docuseries on Matthew Perry, directed by Emmy winner Mary Robertson, features none of his Friends co-stars, a review says, but gains intimacy from that absence. Perry's own voice from past interviews narrates, while longtime friends Roger Castillo and David Pressman and half-sister Mia Perry Bowick share memories, admitting they had feared his death but were shocked by its circumstances.
