Chris Hemsworth celebrated his 33rd birthday on Thursday, and Chris Evans made sure it was out of this world—literally! The actor sent his fellow Marvel star a superhero blooper in honor of the big day.

“Happy birthday to my buddy @chrishemsworth my favorite person to mess up an otherwise flawless take,” he captioned the hilarious clip from the shooting of the first Avengers film. In the video, Evans, as Captain America, flawlessly executes his fighting sequence, while Hemsworth, as the all-mighty god of thunder Thor, has a little trouble catching his hammer, Mjölnir. The actor smiles and laughs as he bounces it around in his hands.

Evans isn’t the only co-star who sent Hemsworth birthday wishes: Mark Ruffalo, who suits up as the Hulk in the Marvel movies, posted a cute video to Instagram of him playfully picking up the birthday boy on the red carpet. “Happy birthday @chrishemsworth. Miss you already #tbt,” he wrote.
