If there is one thing Marvel actors do better than fighting intergalactic threats, it is accidentally spoiling their own movies. The title of Leak Legend has been passed around like Mjolnir at a birthday party. Tom Holland is infamous, yes, he once spoiled Infinity War as if the story was a known fact, but he is hardly alone. Mark Ruffalo live-streamed Thor: Ragnarok. Even Benedict Cumberbatch has had his moments of slip-ups. And now, Robert Downey Jr. may have accidentally joined the Spoiler Squad.

Fans believe Robert Downey Jr. may have spoiled Thunderbolts* with one seemingly innocent Instagram caption: “Just wow!!! Dinner and a show with the Old Avengers. So cool, fresh, and deep. Big congrats. #thunderbolts.” With referring the lot as 'Old Avengers," Downey Jr. has caused crossfire for the fans, who are yet to watch Thunderbolts* and get to know of the "New Avengers." Those who have seen the film gasped in recognition. Those who have not are pacing their living rooms in confusion and rage. Spoiler? Easter egg? Emotional booby trap? Regardless, the fans are livid.

Here is the kicker, Thunderbolts* has been out for just a week. Seven little days. Barely enough time for half the fandom to get tickets, let alone dodge spoilers like Neo in The Matrix. So when Robert Downey Jr.’s post casually referenced “Old Avengers” and a “deep” moment, fans raised eyebrows harder than Nick Fury’s. Theories exploded. One even resurfaced an old Joe Russo interview, where he teased that Downey Jr. was cooking something "doomtastic.” Now everyone is side-eyeing the timeline like it owes them answers, and popcorn.

The popcorn has gone cold, but the fan rage is freshly microwaved thanks to one little post.

Marvel fans were not just upset, they were incinerated. Upon seeing Robert Downey Jr.’s suspiciously emotional caption, a section of the fandom erupted like the Hulk stubbing his toe. Many felt betrayed, others responded with disbelief, and the rest coped the only way they knew how, memes. Some joked he was channeling his inner Victor Von Doom with that line.

However, not everyone is ready to light a spoiler-shaped bonfire. A surprisingly calm corner of the internet is defending Robert Downey Jr., arguing that only those who have watched Thunderbolts would find the caption revealing*. According to them, the outrage is coming from fans doing mental gymnastics while staring at an Instagram post. “It is not a spoiler unless your brain fills in the gaps,” said one tweet, smugly sipping metaphorical tea while chaos reigns below.

So what now? Robert Downey Jr. may have sparked the most accidental fandom feud since Star-Lord slapped Thanos, or he just posted a normal message. Either way, the post is a cultural artifact, proving he still knows how to stir up the internet.
