Show Bizz 411 found a casting call today that does not say Star Wars but is a Disney production being directed by J.J. Abrams.
I feel this tells us that these three characters are to be played by American actors, while the other four characters can be British/European. It could also mean the other roles have been filled, anything is possible.
The updated casting call for actors in New York is as follows:
[YOUNG MAN] Early 20s. Handsome, but not necessarily heroic. He is witty and smart. Physically fit.
[MAN] Late 20s. Physically fit, handsome and confident.
[YOUNG WOMAN] Late teens. Physically fit, raw energy, independent and with a great sense of humor.
So we can assume the call above is modified from this list which hit the internet and Star Wars Insider:
Late-teen female, independent, good sense of humour, fit.
Young twenty-something male, witty and smart, fit but not traditionally good looking.
A late twentysomething male, fit, handsome and confident.
Seventy-something male, with strong opinions and tough demeanour. Also doesn’ t need to be particularly fit.
A second young female, also late teens, tough, smart and fit.
Forty something male, fit, military type.
Thirtysomething male, intellectual. Apparently doesn’t need to be fit.
Star Wars casting news is on fire lately, true or false.
