Anachronisms: Articulated buses in NYC did not exist in 1986. They appeared in revenue service in 1997.
Continuity: When Nicky is at his father's home he is cooking eggs. When he brings the eggs over to the table he has the egg beater and then when the camera angle changes he has a spatula. This goes back and forth a couple of times in this scene.
Anachronisms: Across the street from the theater showing Nicky's new play, there is a poster for the musical, Brooklyn. The musical opened on October 21, 2004, the night after the Red Sox won the ALCS on the way to winning their first World Series since 1918.
