The Latino Review is reporting that Disney and JJ Abrams are considering Ryan Gosling and Zac Efron for roles in Star Wars Episode VII. The role Gosling supposedly is up for is the son of Luke Skywalker (named Ben Skywalker in the books) while Efron's role is unknown. The site also said that Leonardo DiCaprio decided to pass on a Star Wars role to do Robotech The Movie. Now none of this is unsubstantiated so take it with a grain of salt.
Could it be true? If Star Wars was still under George Lucas with JJ Abrams I would flat out dismiss it as I think the pair's instinct is to cast mostly unknowns, especially in the lead roles. Something both have done their entire careers. However, this is Disney and they prefer "named" stars at their movies. They save the newbie castings for their TV shows. This is Star Wars so hiring some famous male or female starlet just for their name strikes me as silly but Disney doesn't think that way. They just think "X star could add y dollars to opening weekend. We need them for Star Wars!". So because of Disney's heavy hand, I am unable to dismiss this rumor as being false.
