Morgan, in its opening weekend, couldn't even crack the weekend top ten after an estimated $615,000 on the Friday it was released in the US, from 2,020 theaters, heading toward a three-day weekend around $1.8 million and a four-day weekend around $2.3 million. It ended up being one of the worst openers of the summer and one of the worst openings for a film debuting in over 2,000 theaters. The film was subsequently pulled from theatres after 2 and a half weeks.
When Dr. Weathers first meets Morgan, the music playing is the countertenor (originally soprano castrato) aria, "Ombra mai fu", the opening aria from the 1738 opera, "Serse" ("Xerxes") by George Frideric Handel. The aria is often referred to as "The Aria of Love" and is often used, with or without lyrics, as incidental music at weddings. The music (sans vocals) alone is known as Handel's "Largo" because of the tempo signature of the piece.
Takes place in New York State, based on car license plates.
