The Avengers 3 Infinity War: Several confirmed characters at the cast?

And if Sean Gunn, brother of James Gunn, had revealed the presence of several characters in The Avengers 3 Infinity War?
Fans of the Galaxy 2 Guards will be delighted: several characters in the film could be present in The Avengers 3 Infinity War. This rumor was born with Sean Gunn, brother of James Gunn, who published a mysterious photo on his Instagram account staff . We discover the actor with a cap and a mug with the image of the film as well as a legend “I work on a new secret project, I can not tell you anything”. Obviously, with several references to The Avengers 3 Infinity War – whose shooting began – on the plate, impossible not to think about it. But then what characters Guardians of the Galaxy could be present in this super-heroic meeting?
The face of Sean Gunn will probably tell you not much but while Bradley Cooper is the voice of Rocket Raccoon, the brother of the director gives the character to life through motion capture . A new proof – if needed – that the giant raccoon will be present. But Sean Gunn also embodies Kraglin in Guardians of the Galaxy 2 wherein Drax could fight with an Avenger , leaving it unclear as to his presence in the film of the Russo brothers. You’ll understand in Infinity War , the heroes will be many on the screen. It’s simple, with its huge budget, this film MCU could well be the biggest film based on comics ever shot!
