The Chainsaw Scene Scarface
The scene that earned Scarface its X rating was based on a real Miami police report
The chainsaw scene — beat 6 in the beat sheet — takes place early in the film, when Tony Montana and his associate Angel attempt to buy two kilos of cocaine from Colombian dealers led by Hector the Toad at a Miami Beach hotel. When the negotiation breaks down, the Colombians suspend Angel from the shower curtain rod and dismember him with a chainsaw while Tony watches, unable to act. Tony eventually grabs a gun, shoots his way out, and escapes with both the cocaine and the money.
Oliver Stone based the scene on an actual Miami police report describing a nearly identical drug deal that went catastrophically wrong. The specificity — the hotel room, the shower rod, the chainsaw as instrument of coercion — came from the real case. (mentalfloss)
De Palma staged the violence to suggest more than it shows
The scene's reputation as one of the most graphic sequences in mainstream cinema is partially a product of misdirection. Most of the chainsaw violence occurs offscreen. The camera holds on Pacino's face — his horror, his calculation, his survival instinct — while the sounds of Angel's dismemberment play on the soundtrack. The viewer's imagination fills in the visual detail that the camera withholds.
There was one explicit shot — Angel dangling from the shower rod with his severed arm also swinging from a chain before his leg is cut off — that De Palma always intended to remove from the final cut. He wanted to suggest more carnage than was actually depicted, using the audience's imagination as his most effective tool. The MPAA, focused on the explicit shot, pushed for cuts that De Palma had already planned to make. (screenrant)
The scene was the primary target of the MPAA's X rating
The chainsaw sequence was the focal point of the MPAA's decision to rate Scarface X — not once but three times. While the board cited "excessive and cumulative violence and for language" as their overall reasoning, the chainsaw scene was the specific sequence they could not accept at the R level. The sustained tension, the sound design, and the combination of torture with drug-deal realism pushed the scene beyond what the ratings board considered appropriate for a restricted audience.

De Palma submitted four progressively edited versions. The board rejected all of them. The resolution came through an appeal that Bregman won 18-2, after which De Palma released the original uncut version anyway. See Critical Reception and Legacy (Scarface).
The scene functions as Tony's audition — survival under maximum pressure
Structurally, the chainsaw scene is the film's first turning point. Before this scene, Tony is a dishwasher with ambition. After it, he is a man who has proved — to Frank Lopez, to the audience, and to himself — that he can endure the worst the drug world can inflict and emerge with both the product and the profit. Frank's invitation into the organization in beat 7 is a direct consequence: Tony survived what Frank's other men could not.
The scene also establishes the film's moral calibration. Tony does not enjoy the violence — his face registers genuine horror as Angel is killed. But he endures it, recovers, and converts the catastrophe into professional advancement. The pattern — surviving violence and converting it into upward mobility — repeats through beats 18-19 (surviving Frank's assassination attempt and killing Frank) and inverts in beat 28 (refusing the car bomb and triggering his own destruction).
