When it comes to enthusiasm, few Marvel actors can match Tom Holland — and few have had to manage that enthusiasm more than Robert Downey Jr. The veteran actor, who mentored Holland both on-screen as Tony Stark and off-screen as a friend, once came up with a uniquely “Iron Man” solution after Holland nearly spoiled major Avengers secrets — three times.
The Day Tony Stark Went into Damage Control
According to a Marvel insider, the incident took place during the filming of Avengers: Infinity War. After Holland’s third near-spoiler moment in front of the press, Downey decided to intervene — in his own theatrical, good-humored fashion.
“Robert walked over to Tom, put a hand on his shoulder, and said, ‘Don’t you dare say it,’” the insider recalled. “Then he handed him a folded piece of paper and told him, ‘Sign this — it’s a Spoiler Contract.’”
The document, written in Downey’s signature tongue-in-cheek style, quickly became a piece of Marvel lore — a joke with a serious point.
The Iron Rules of Spoiler Prevention
Holland later revealed the story on Jimmy Kimmel Live!, reading aloud what he called “Downey’s five sacred rules.” They were:
-
Thou shalt not reveal anything unless Kevin Feige says so.
-
No interviews without adult supervision (preferably Benedict Cumberbatch).
-
Don’t trust live microphones — ever.
-
If asked about Tony Stark, cry, but say nothing.
-
When in doubt, just say, ‘It’s all very emotional.’
Holland admitted he kept the handwritten “contract” pinned in his trailer for the rest of the production. “Every time I’d start talking too much during an interview,” he said with a laugh, “Robert would just yell across the room, ‘Rule number three, kid!’”
A Mentor with Iron Humor
The playful exchange perfectly captured their off-screen relationship. Director Joe Russo, who co-helmed both Infinity War and Endgame, described the bond between the two actors as a reflection of their characters.
“Robert took Tom under his wing the same way Tony Stark guides Peter Parker,” Russo said. “But he also knew how to have fun with it — especially when Tom talked too much.”
Downey’s mentorship extended beyond just keeping secrets. Cast members often noted how the senior actor modeled professionalism on set, encouraging younger performers to balance passion with discretion — a vital skill in the tightly controlled Marvel universe.
The Spoiler Legacy Lives On
For his part, Holland has learned to embrace his “spoiler curse” with humor. During the Avengers: Endgame press tour, he famously admitted that the studio gave him incomplete scripts to prevent accidental leaks. “They gave me fake scripts,” he laughed. “I thought I was filming a wedding scene — it turned out to be a funeral.”
Today, Holland credits Downey’s mentorship — and that now-legendary contract — for teaching him restraint.
“Robert basically trained me how to shut up properly,” Holland joked.
And somewhere in the Marvel archives, fans like to imagine, that folded piece of paper still exists — the Spoiler Contract that kept Spider-Man from giving away the end of the universe.
