Annie Hall

In the scene where Alvy meets Annie's family for the first time, Allen uses humor and anti-mimetic elements to provide the tone for the scene. Right after he compliments the ham, Alvy is transformed into a Hasidic Jewish stereotype. This reinforces Allen's idea of perception vs. reality. We know that he is not really like that, but their prejudices don't allow them to see him in any other way. Because of this anti-mimetic tone, the viewer is unsure of whether to trust what they're seeing or not. There's no real way to tell if when Alvy's jokes are met with silence if the family really didn't find him humorous or if we are seeing the version that only happened inside his head.

Part 2:
2. Many of the scenes in Annie Hall could be classified as "magic realism." The film blends together reality and fantasy in a way where the two are intertwined and the same. In the movie theatre scene, Alvy remarks "Wouldn't it be great if life were really like this?" and after he finishes his first play and we see his character and Annie's working out in the end, he says to the camera something along the lines of "we all want things to work out in the end." Allen does a good job of creating a film that is a good mix of life as we know it is and life as we want it to be.
3. The subtitle/audio disconnect is meant to let viewers in on the character's inner thoughts and motivations and depict the awkwardness of getting to know someone for the first time. The actual dialogue is convoluted and pretentious and it is clear that both characters are trying to portray themselves as a potential partner and responsible, intelligent human being. The subtitles however, let the audience know what they're really feeling and where their true hearts lie.
