The line comes from Tropic Thunder, the 2008 satirical war comedy, where Robert Downey Jr. plays Kirk Lazarus, an Australian method actor who has taken his role so far that he is playing a character inside another character. The quote became a widely shared movie moment because it neatly sums up the film's joke about extreme method acting. As clips circulated on video platforms and soundboards, creators began reusing it whenever someone was performing, impersonating or hiding behind a second identity, keeping the line alive long after the film's release.
