Before he was a movie star, Timothée Chalamet was an up-and-coming Xbox 360 controller modder
Chalamet had a YouTube channel called ModdedController360

Everyone has to start somewhere. This holds true even in the case of still-pretty-youthful movie stars like Timothée Chalamet. He prepared for his current ascent to the upper echelons of Hollywood—and the titles of Padishah Emperor and Kwisatz Haderach—by hosting a YouTube channel where he sold customized Xbox 360 controllers.
Vice enlisted the help of, no joke, “a security expert who investigates war crimes” for a look into the question of whether or not a YouTube channel called ModdedController360 (which last uploaded a video in 2010) belonged to Chalamet.
The publication’s attention was piqued by long-standing rumors that the anonymous boy selling cool 360 controllers painted in various patterns (red and black tiger stripe; blue and silver; a festive green and red) and shouting out Call Of Duty: Modern Warfare 2 as the “best video game out there right now” was a baby Chalamet. And so, it embarked upon an “open-source intelligence investigation.”
