Tear Jerker: The Truman Show
Truman crashing into the wall of the studio. Feeling that he is trapped forever, he begins to break down in tears as he tries to punch through the wall in a futile manner.
Truman being reunited with his (actor) dad as part of a ploy of Christof's to keep Truman on the island. While Christof is manipulating the scene with rising music and dramatic shots, the real, genuine emotion of Truman at once makes the scene work In-Universe but also for the actual audience in terms of dramatic irony, how Truman is just a part of the emotional pandering itself, without his knowledge.
