In a clever new Twitter message referencing the Hulk and Moon Knight, Mark Ruffalo says he's learned his lesson the hard way when it comes to Marvel spoilers. In the Marvel Cinematic Universe, Ruffalo is known as Bruce Banner/Hulk, having taken up the role from Edward Norton, who starred in The Incredible Hulk. Ruffalo first appeared as the Green Goliath in 2012's The Avengers and has continued to do so in the Marvel Cinematic Universe ever since. He'll hulk out next for Tatiana Maslaney's Disney+/Marvel series She-Hulk.

Ruffalo has not been formally announced as part of Marvel's upcoming film, Moon Knight, but a recent story that focused on the coincidence of him being in Budapest at the same time and place as the project's lead star Oscar Isaac piqued the actor's interest, and he posted the story via his Twitter. Ruffalo was eager to point out that he'd learned his lesson about spoilers the hard way, claiming that he's in charge of the MCU's next phase, which may be a bit of a reveal in and of itself.

Marvel's Moon Knight is set to premiere in the year 2022, and will officially star Oscar Isaac and Ethan Hawke, among others.
