Mark Hamill wants a role in 'Guardians of the Galaxy Vol. 3' after he is now an "unemployed actor". The 66-year-old actor is best known for starring as Jedi Master Luke Skywalker in the hit sci-fi franchise 'Star Wars', but in a recent Twitter conversation with the 'Guardians of the Galaxy' filmmaker James Gunn, it seems Hamill wants to join another space franchise. The awesomeness of it might end me, but I'm willing to risk it.
