Scott portrayed the lead role of Evan in horror film "Bloodline" (2018). Executive producer of "Bloodline" Emma Tammi praised Scott's performance and acting skills by saying: "He has an amazing theater background and is a very versatile actor, and I don’t think most of the world has seen that yet. He was excited to approach this character in a way that would surprise people, and he really nails it." In May 2018, it was announced that Scott was cast as the new series lead in Fox's "Lethal Weapon" as a new character named Wesley Cole, replacing Clayne Crawford as Martin Riggs. Darren Franich of "Entertainment Weekly" praised Scott's addition to the cast and called his performance "charming". On May 10, 2019, Fox canceled the show after three seasons. Scott portrayed abusive stepfather Martin in the coming-of-age road film "Already Gone" (2019), which was executive produced by Keanu Reeves.
