27. Stallone's Cameo
Despite the many rumours of who he was set to play, Sylvester Stallone turns up pretty early in the film playing Ravager Stakar - better known in the comics as Starhawk, a hero who was part of one iteration of the Guardians Of The Galaxy team.
That explains why the sequel's working title was Guardians 3000 (as listed in Production Weekly Issue #942). He was of course the founder of the Guardians Of The Galaxy in the 31st Century, and appeared alongside Major Victory, Yondu, Martinex and Charlie-27 in that line-up.
Starhawk also appeared as part of the extra features on the Guardians of the Galaxy Blu-ray. He was included as a character in “Galactic Adventurer” – an 8-bit retro game animation...
James Gunn previously said that he loves Starhawk and promised to reveal one of his personal favourite characters in the sequel.
Later, he also mentions the "Colours of Ogord", which is Starhawk's surname in comics lore after he was adopted by a character of the same name.
