The last names of the "Capuletti" family characters, headed by "Monty Capuletti" aka "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 play "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 movie was the "first major starring role of Rodney Dangerfield" according to the Australian DVD sleeve notes whilst 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 [to date, 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 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 popular singer-pianist-composer-songwriter Billy Joel. The catchy tune bookends the movie, is heard on 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 a homage to both James Brown and Wilson Pickett.
The conditions of the will that Monty Capuletti (Rodney Dangerfield) had to adhere to 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/overeating clause. Jokingly, a class action from public paying audiences against the film's marketers for false advertising could have eventuated.
