A Shock to the System (1990 film)
A Shock to the System is a 1990 American black comedy film directed by Jan Egleson and starring Michael Caine, Swoosie Kurtz, Elizabeth McGovern, and Peter Riegert. It is based on the 1984 novel "A Shock to the System" by British author Simon Brett. The film was released on March 23, 1990 and received generally positive reviews from critics. Plot. Graham Marshall, a long-time executive in a large advertising company, is unexpectedly passed over for promotion in favor of his obnoxious younger rival Bob Benham. While he sympathizes with his friend George  Brewster, whose dismissal in the midst of a corporate takeover created the open position, Marshall is angry and disappointed. His greedy, self-absorbed wife Leslie is devastated and continually reproaches her husband for his apparent lack of ambition and willpower. The night of the missed promotion, Graham is waiting for his train on the subway. An aggressive panhandler harasses him for being so rich and ungenerous. In a fit of rage, Graham pushes him hard enough that he falls on the subway tracks and gets run over by an oncoming train. Marshall is able to leave unobserved, which unexpectedly elates  him. Deciding to take revenge on the people who have made his life miserable, Marshall starts meticulously planning their deaths. Recalling an incident in which he was almost fatally electrocuted by faulty wiring in his basement, he arranges for Leslie to have a similar accident. After her death, he gets more ambitious and plans to get rid of Bob. First he rents a car using George's corporate account and procures a bottle of heavy downers from an office courier who deals drugs. While on a date with Stella Henderson, a female employee who is romantically interested in him, he  spikes her drink with some of the downers and waits until she passes out. Driving the rental car to Bob's boat, he booby-traps it by tampering with a natural gas tank and taping some matches to the door. While returning home, he victoriously lights a cigar and absent-mindedly leaves his personalized gold plated lighter on the dashboard before returning the car to the dealer and going home. The next morning Stella wakes up as expected and assumes she blacked out after having slept with Graham. They spend the morning having sex to further cement Graham's alibi . Bob and one of his brown-nosing subordinates board his boat; opening the door, they ignite the gas tank and blow themselves up. In the wake of Bob's death his boss, Mr. Jones, reaches out to Graham and offers him the promotion. He accepts it and, while discussing Bob's death, Jones casually mentions his interest in flying planes. As Graham settles into his new position, life becomes increasingly hectic. Police Lieutenant Laker, assigned to all the deaths surrounding Graham, is quickly convinced of his guilt but lacks any evidence. Graham realizes his lighter has gone missing and slowly  realizes that he must have left it in the rental car. Interviewed by Laker, Stella begins to suspect that Graham really is a killer. She retrieves the lighter from the car rental company and plans to meet Laker on the same subway platform where Graham earlier killed the panhandler. Graham finds her first and, during a tense confrontation, he appears to contemplate pushing her onto the tracks. However, after expressing her deep disappointment with him, Stella hands over the lighter and leaves without further incident. As Graham exits the subway station, he runs into Lt. Laker and victoriously lights a  cigar with his retrieved lighter right in his face. Without evidence, Laker has no choice but to let Graham go. Meanwhile George, intensely depressed about his forced retirement, finds Graham's stash of downers and kills himself by taking the rest of them all at once, not realizing his knowledge of the car rental on his corporate account could have implicated Graham. Graham revels in his newfound prestige and freedom, having eliminated all his enemies and gotten away with it, while ensuring Stella's silence by transferring her to Los Angeles. However, there is one more tiresome detail to deal  with: Jones refuses to give up his corner office. As Graham continues to narrate, Jones's plane is seen flying over some tropical islands, before encountering sudden engine trouble. The movie ends with the sound of an explosion and Graham looking satisfied with himself. Difference from the novel. The movie plot differs somewhat from the novel. In the novel, Graham kills the panhandler by clobbering him to death with a golf cart he got as a gift and throwing his body off a bridge into a river below. Then when he tries to kill his wife, he begins with a  failed attempt involving him awkwardly buying some poison from a florist after acting very suspicious and lacing a whiskey bottle that his wife drinks constantly from with it so she will drink it and die. However, it turns the whiskey blue and it smells terrible and he knows there's no way she would ever drink it, so he abandons the idea and stashes the bottle in his shed. Then he kills his wife the same way as the movie and kills his boss the same way as the movie (even though his brown-nosing subordinate survives the explosion with  only some scars on his face and then proceeds to brown-nose Graham once he gets the promotion). His missing lighter gets resolved differently by his old boss George getting it since the car was rented in his name. He gives it back to Graham without realizing how damning it could have been to the police and Graham silences him by pushing him in front of a subway train to make sure he never talks to anyone else about it. Both the novel and movie end with Graham getting away with all of his killings. However, the novel then throws  a final twist of irony at the end. There's a subplot featuring his mother-in-law, who is certain that Graham killed her daughter and is persistently trying to prove it. After Graham taunts her with the knowledge that he will never be prosecuted for it, he returns home from work one day to find Lt Laker preparing to arrest him. It turns out his mother-in-law found the poison laced whiskey bottle in his shed and she drank it and made a big show in front of his neighbors about how he tricked her into drinking it  before dropping dead in front of everybody. That combined with the florist testifying about how awkward he acted when he bought the poison and a scorned Stella falsely testifying about how Graham always complained about how much he hated his mother-in-law, it looks very bad for Graham. After getting away with 4 murders, he is about to be arrested for a murder he did not commit. Production. The film was shot in New York City between May 22 and July 28, 1989, on a $10 million budget. Scenes were shot at Wall Street Plaza and Grand Central  Terminal. The sailboat scenes were filmed on Lake Montauk. According to Corsair Pictures executive Frank Perry, the screenplay originally ended with the character of Graham Marshall being killed off but was rewritten because of Caine's performance.
