The last names of the "Capuletti" family characters, headed by "Monty Capuletti" a.k.a. "Montgomery Capuletti" (Rodney Dangerfield), and the Monahan family, headed by Mrs. Monahan (Geraldine Fitzgerald), were a spoof and a reference to the names of the two feuding families in William Shakespeare's "Romeo and Juliet", the Montagues and the Capulets. Easy Money (1983)'s story-line features familial conflict between Monty and his mother-in-law.
The name of the song that Monty Capuletti (Rodney Dangerfield) sang at his daughter's wedding was the traditional Italian tune of "Funiculi, Funicula" by Luigi Denza and Peppino Turco with the latter billed as G. Turco (as with his birth name of Giuseppe Turco).
The picture was notable for featuring a title song track of the same name sung by Billy Joel. The tune bookends the movie, is heard in the film's trailer, and was included on Joel's 1983 album "An Innocent Man". The "Easy Money" song, according to an interview with Joel, is an homage to James Brown and Wilson Pickett.
The movie was the "first major starring role of Rodney Dangerfield" according to the Australian DVD sleeve notes, while similarly, film critic Leonard Maltin has commented that the film was "Dangerfield's first starring comedy vehicle."
Debut cinema movie directed by James Signorelli. The picture is the first of only two theatrical feature films (as of June 2014) directed by Signorelli, the other being Elvira: Mistress of the Dark (1988). Signorelli's career has predominantly been in video and television.
The original television broadcast version of the movie (not included on any video release) featured a night at the fights for Monty and friends, where Monty's stress immediately after losing his job, causes him to hallucinate and flee the arena (right before he's seen watching television, and informs Rose that he lost his job).
The conditions of the will, to which Monty Capuletti (Rodney Dangerfield) had to adhere for one year, were No Smoking, No Philandering, No Gambling, No Drugs, No Alcohol, and that he must weigh no more than 175 pounds, which was interpreted as No Overeating. Movie posters for the film stated conditions not actually mentioned in the film. These were No Cheating, No Booze (substituting for No Alcohol), No Nothin', and No Pizza, though the latter did relate to the weight clause. Jokingly, a class action from public paying audiences against the film's marketers for false advertising could have eventuated.
