Kirk Lazarus is the fictional Australian method actor played by Robert Downey Jr. in the 2008 satirical war film Tropic Thunder, a comedy about actors filming a Vietnam War movie who become caught in a real conflict. The short we lost line fits Lazarus's intense, deadpan screen presence and has circulated online as a compact reaction clip for defeat. Because it needs no setup, creators reuse it whenever a plan, game or argument has clearly gone wrong, keeping the moment instantly recognisable years after the film's release.
