During San Diego's Comic-Con, it was revealed that Sylvester Stallone has a part in Guardians of the Galaxy 2.
The legendary action star showed up briefly in the footage shown - appearing in just a single one-second shot.
Director James Gunn subsequently explained (via Cinema Blend): "It's a very, very key, important role. It's not a huge role. He's a great and key supporting actor."
Today (July 26) has also seen Gunn unveil LOADS of new cast members, and they all look pretty darn terrifying.
A new image posted on Instagram shows off nine of the villainous Ravengers from the upcoming Marvel movie.
