The Performance (2019)

In an attempt to impress his younger brother, actor Marvin Bigsby arrives at his middle school career day. While going into a Q&A portion discussing what he's accomplished in his career, Marvin becomes sensitive. Both he (and the children) realize his job has not amounted to much. Growing more erratic by the second, Marvin goes into a tear, telling the kids the hard truths about life as a struggling artist.
