Manley, who posts online as "lukeylunchb0x" and "FatrickEwing," first rose to internet notoriety through a June 3, 2021
Sidetalk video about
Trae Young and the
New York Knicks during the
2021 NBA playoffs. The same month, he gained further attention via posts on
Humans of New York and by
New York Nico. He was later featured in content created by
Barstool Sports. Director Josh Safdie and casting director
Jennifer Venditti discovered Manley through his
Sidetalk and New York Nico appearances. Safdie developed the role of Dion Galanis for him while writing
Marty Supreme. Venditti's casting process included a lengthy on-camera personal interview and improvisational scenes. For a scene requiring him to act angry—an emotion Manley said did not come naturally to him—he asked Chalamet to berate him off-camera to provoke the reaction. The film opened theatrically in the United States on December 25, 2025. == Personal life ==
