Avengers: Age of Ultron was the second Marvel movie from director Joss Whedon, picking up the story after the events of The Avengers, Iron Man 3 and Captain America: The Winter Soldier, among others. The Marvel film saw the Avengers come together to take down an AI created by Tony Stark (played by Robert Downey Jr.), Ultron (James Spader), who was originally intended to protect Earth but who goes off-track and instead turns on humanity in a bid to eradicate them.
Age of Ultron also introduced audiences to another of the Infinity Stones — the Mind Stone — which would go on to become crucial to Thanos’ (Josh Brolin) plan to wipe out 50 per cent of the population of the universe.
But one scene features a tiny yet awkward gaffe on the part of Captain America star Chris Evans.
Exposing the moment on Reddit, one fan shared a clip of Captain America, Thor (Chris Hemsworth) and Iron Man discussing the Stones.
At the end of the film, Thor voiced his suspicions something bigger was afoot with the Infinity Stones, foreshadowing Thanos’ plot.

“Someone has been playing an intricate game and has made pawns of us. And once all these pieces are in position…”
“Triple Yahtzee?” Stark chimed in.
Throughout the clip, the trio are walking through one of the hallways at the New Avengers Facility, deep in conversation.
