Danny Messer (Carmine Giovinazzo) says "I've got my sea legs". This line is a reference to dialog from Forrest Gump (1994). Gary Sinise (Mac Taylor) portrays "Lieutenant Dan Taylor", a man without legs, who says "I thought I'd try out my sea legs".
The term "Manhattanhenge" was coined in 2002 by American Museum of Natural History astrophysicist Neil deGrasse Tyson. The dates of these aligned sunrises and sunsets do not match the actual solstices and equinoxes because Manhattan's street grid are skewed 29 degrees from the compass directions.
