I Know This Much Is True (2020)

"I Know This Much Is True" is the HBO limited series adapted from Wally Lamb's novel, following identical twin brothers whose lives unravel across decades of family trauma and mental illness. Mark Ruffalo carries the dual lead role with a demanding physical and emotional performance, playing both brothers with distinct rawness. The series doesn't shy away from bodily exposure either, and fans looking for Ruffalo unclothed on screen will find 3 scenes archived here, including nude and sex scene content that adds a stripped-down intimacy to the show's heavier themes. It's a prestige drama with real skin in the game, literally and otherwise.
