American docu-comedy television series created, written, directed by and starring Nathan Fielder. The Rehearsal features a character played by Nathan Fielder who helps ordinary people rehearse upcoming difficult conversations or life events through the use of sets and actors hired to recreate real situations. The situations can be trivial, like confessing to a lie about educational history, or more complex, like raising a child.
Fielder commissions extravagant sets with every detail recreated, and hires actors to inhabit these sets and practice different dialogue trees with his clients dozens of times to try to prepare them for every variable. Information used to train the actors and build the sets is often collected without the subjects' knowledge (this aspect, however, is often played with a comedic effect).
