Get your tissues ready, because we're about to see Timothée Chalamet [1] in an entirely new light [2]. After Amazon Studios released the first two teasers and an official trailer from the upcoming film Beautiful Boy, we have a brand new trailer to unpack. In the two-minute video, we get a brief glimpse of Chalamet's transformation [3] from a lighthearted, suburban big brother enjoying Wednesday night family dinners, to a young adult battling a gruesome methamphetamine addiction. The movie, which is set to release Oct. 12 [4], is based on David Sheff's gut-wrenching memoir about his son Nic's spiraling addiction and the heartbreaking impact it had on every person around him (Steve Carell [5] will be playing Nic's father). Beautiful Boy is a far cry from Chalamet's sweeping Italian romance [6] in last year's hit Call Me by Your Name [7], and it will shake you to your core.
