5 Celebrities Sylvester Stallone HATED in Real Life

Sylvester Stallone is known worldwide as a legend of action cinema, the man who gave us Rocky and Rambo. But behind the scenes, he’s not always the calm, collected hero we see on screen. Over the years, Stallone has had his fair share of feuds, rivalries, and outright hatred toward certain celebrities. Some of these clashes were explosive, while others quietly simmered for decades. Here are five celebrities Stallone couldn’t stand in real life.

1. Arnold Schwarzenegger

For years, Stallone and Schwarzenegger were bitter enemies. During the height of the ’80s action-movie boom, both men competed for box office dominance. The feud escalated so much that Stallone admitted he “hated” Arnold at one point.

It went beyond competition—Schwarzenegger even tricked Stallone into taking the flop film Stop! Or My Mom Will Shoot by pretending he wanted the role. Stallone later called it one of the worst decisions of his career. Luckily, the rivalry eventually cooled, and the two even became friends, but for a long time, the hatred was real.

2. Richard Gere

Their beef started on the set of a movie that never even got finished. Stallone and Gere were cast together in The Lords of Flatbush (1974), but the two clashed immediately. Stallone said Gere was “too rough” on set, especially during fight rehearsals. Things boiled over when Gere supposedly spilled food on Stallone during a break.

Stallone had him fired from the film, and to this day, the two actors still don’t get along. Gere has even admitted he believes Stallone spread the nasty rumors about him being into “gerbils,” something Stallone has denied.

3. Bruce Willis

You’d think action heroes stick together, but Stallone and Willis had a money-fueled falling out during the Expendables franchise. Stallone publicly blasted Willis on Twitter after negotiations fell apart, calling him “greedy and lazy.”

The feud shocked fans since the two had once been close through Planet Hollywood (their joint business venture with Schwarzenegger). They eventually patched things up, but Stallone made it clear—he was furious at Willis’s attitude.

4. Jean-Claude Van Damme

Back in the ’90s, Stallone and Van Damme nearly got into a physical fight at a party. According to multiple witnesses, Van Damme challenged Stallone and even tried to fight him outside the club. Stallone later said he was amused by it but admitted he thought Van Damme was “out of his mind.”

The two eventually starred together in The Expendables 2, but the tension between them was still obvious behind the scenes.

5. Steven Seagal

Stallone has always had issues with Steven Seagal, and the two action stars openly disliked each other. Stallone once said Seagal carried himself with arrogance, refusing to mingle with other stars. Their beef became so heated that during a Hollywood party, Seagal avoided a showdown with Jean-Claude Van Damme—something Stallone mocked him for.

To this day, Stallone has never spoken warmly about Seagal, and fans know the bad blood was very real.

Final Thoughts

Sylvester Stallone may be a Hollywood legend, but his career has been shaped not only by his iconic roles but also by his fiery personality. His rivalries with these stars prove that even the toughest men on screen aren’t immune to grudges and clashes behind the curtain.
