**The rivalry between action icons Arnold Schwarzenegger and Sylvester Stallone in the 1980s and ’90s was not just professional competition; it was an escalating game of one-upmanship. This bitter, decade-long war came to a head in 1992 with a single, genius act of sabotage by Schwarzenegger, tricking Stallone into starring in a film so notorious that the actor still groans about the damage: the film Stop! Or My Mom Will Shoot. The fallout was immense, sparking three years of cold war between the titans, with Stallone later lamenting the ordeal in a phrase that quantified the true price of the prank: “It Cost Me 20 Million.”
The Prank: Faking Interest in “Garbage”
The feud was built on box office receipts and the relentless quest for the title of the world’s biggest action star. This intense psychological competition provided the perfect opportunity for Arnold Schwarzenegger to deploy his ultimate prank.
The film in question, Stop! Or My Mom Will Shoot (1992), a buddy-cop action comedy, was universally deemed a terrible script by those who read it. Schwarzenegger, who was first offered the lead role of Sergeant Joe Bomowski, immediately recognized the script as “a piece of garbage.”
Instead of simply declining the project, Schwarzenegger leveraged the intense rivalry with Sylvester Stallone. He feigned tremendous interest in the film, letting studio executives and his own agent know he was “actively considering” the role, thus sparking a bidding war for a property he planned to reject.
The psychological trap worked perfectly. Hearing that his nemesis was keen on the part, Stallone’s competitive instinct kicked in. He reportedly rushed to sign on, motivated entirely by the desire to snatch the project away from Schwarzenegger. Schwarzenegger was reportedly delighted, admitting his strategy was simple: “The only way I could catch up with him is if he had a stumble.”
The Critical and Financial Data of the Disaster
Stallone’s performance as Sergeant Joe Bomowski, a tough cop paired with his eccentric, overbearing mother (Estelle Getty), was a critical catastrophe.
| Metric | Data Point | Significance |
| Critical Rating | Disastrous 4% approval rating on Rotten Tomatoes | Stallone called it “maybe one of the worst films in the entire solar system.” |
| Budget vs. Gross | $45 million Budget vs. $70.6 million Worldwide Gross | A profound box office underperformance for a star of Stallone’s caliber. |
| Reputational Cost | “It Cost Me 20 Million” | Stallone’s estimate of lost earnings and reputational damage. |
The “It Cost Me 20 Million” quote, while likely a generalization of the reputational damage and lost opportunity cost, is grounded in the film’s disappointing commercial data. The underperformance, factoring in marketing costs, resulted in a significant loss of career momentum for Stallone.
Related Notable Event: Three Years of Silent War and The Expendables
The consequences of the prank were a prolonged period of frigid distance between the two stars, defined by veiled insults in the press rather than direct communication. This “silent Hollywood war” only began to thaw years later, culminating in their major collaborative notable event:
-
Film: The Expendables (2010)
-
Significance: The film, directed by Stallone himself, featured a joint cameo by the two titans, a public sign that the wounds of the Stop! Or My Mom Will Shoot debacle had finally healed and their rivalry had evolved into a shared celebration of their action legacy.
The incident remains a legendary piece of Hollywood lore—a testament to the fierce, calculating ambition that defined the biggest action stars of the era, and the high price paid when professional rivalry trumped creative judgment.
