"Do or do not. There is no try." (t88ification/tumblr)

Thousands of fans have gone to Troy, MI to audition for the two roles, hoping to be a part of one of the world's biggest science fiction cults. As Marshall said in "How I Met Your Mother," "the only people in the universe who haven't seen Star Wars are the characters in Star Wars and that's 'cause they lived 'em."

Who doesn't want to be in the new "Star Wars" trilogy? Here is what the official casting sheet says and our guess of who can can fit in these roles:

The "Lonely Bones" star (celebritiesandmovies/tumblr)

FEMALE ROLE

Seeking young woman to play 17-18 year old. Must be beautiful, smart and athletic. Open to all ethnicities (including bi and multi-racial) Must be over 16. 

RACHEL - Was quite young when she lost her parents. With no other family, she was forced to make her way in a tough, dangerous town. Now 17, she has become street smart and strong. She is able to take care of herself using humor and guts to get by. Always a survivor, never a victim, she remains hopeful that she can move away from this harsh existence to a better life. She is always thinking of what she can do to move ahead 

1. Saoirse Ronan

She's young and she's experienced. Saoirse has played major roles in "The Host," "The Lovely Bones," and "Atonement," she is no stranger on the big screen. Perhaps she will be a great addition to the Star Wars movies and break out as the next Natalie Portman?

The latest "Doctor Who" companion definitely proves to fit the role of a beautiful, smart and athletic young woman in her adventures with the Doctor. She has taken up more TV roles than roles in feature film but she has already made her big screen debut in "Captain America: The First Avenger." She is soon to star in the new "Doctor Who" 50th anniversary film "The Day of the Doctor" which shows her potential to transit from TV to film. 

3. Rose Leslie

Any Game of Thrones fans would recognize her as Ygrite, the red hair wilding that lives north of the Wall. Although she is still a new face to the big screen, her performance in Game of Thrones have proven that she can take on a role of a strong, independent woman. 

MALE ROLE

Seeking young man to play 19-23 years old. Must be handsome, smart and athletic. Must be over 18. 

THOMAS - Has grown up without a father’s influence. Without the model of being a man, he doesn’t have the strongest sense of himself. Despite this he is smart, capable and shows courage when it is needed. He can appreciate the absurdities in life and understands you can’t take life to seriously.

1.Nicholas Hoult 

Hoult has a remarkable filmography for his age, debuting on big screen in "About a Boy" to participating in films like "X-Men: First Class," "A Single Man," and "Warm Bodies." He is no stranger to TV audiences to having played Tony Stonem in "Skins." His experience in film will make him a safe choice for Thomas.

2. Freddie Highmore

From being Charlie in "Charlie and the Chocolate Factory"  to being Norman Bates in the new TV series "Bates Motel," Highmore is young and looks to have great potential in the future having already participated in different genres of film and TV. He has started acting at the age of 7 and Johnny Depp actually specifically requested him to play Charlie Bucket in the film.Although he has said that he does not plan to continue acting as an adult, being in the "Star Wars" trilogy is something I guess even he can't refuse. 

3. Logan Lerman

Slowly coming to the public's eye, Lerman has been participating in more and more major films like the "Percy Jackson" series and "The Perks of Being a Wallflower". He will also be starring in the much anticipated film "Noah" which will be in theaters next March. Perhaps he will be able to take on this role of a handsome, smart and athletic man in the new "Star Wars" movie.
