Oscar-nominated screenwriter Charlie Kaufman visited set during the filming of the "This Is How We Do It" sequence.
Fred Armisen is actually a vegan in real life, so the ham he ate on set was not real meat.
A very careful viewer with an expensive television will notice a dolphin jumps out of the water behind June as she approaches the hammer.
The furniture falling in front of June was shot separately, without Maya Rudolph on set. Maya then had to react to the furniture as if it was actually falling in front of her, and the two sequences were then combined in post-production.
June and Oscar lying on the beach after she chases him down was filmed during a massive rainstorm. The actors only had limited takes to complete the scene due to the dangerous weather approaching.
