Nathan Fielder, best known for his Comedy Central show, Nathan For You ( and cringe comedy ), writes, directs, and stars in this brand-new HBO series. The artist goes to incredible lengths in the show to allow viewers to improvise moments before they actually occur. In the first instance, Fielder assists a person in getting ready for a revelation to a buddy and constructs an exact duplicate of the bar they’ll be meeting at ( the attention to detail is amazing ). We see how the actual change between the two friends turns out after making plans for any outrageous events. The Rehearsal may spend some time on your screen, which is crazy and absolutely fascinating.
