As the protagonist in the movie, Luke Skywalker's choice directly determines the success or failure of the movie. Mark Hamill, who was only 24 years old at the time, was a TV actor and was planning to develop in the direction of film. His energetic appearance and easy-going attitude were immediately appreciated by director George Lucas.
As another protagonist in the movie, the space smuggler Han Solo directly changed the fate of the current movie superstar Harrison Ford. Harrison Ford had only temporarily appeared in Hollywood before, and was not well-known. Because he was still working part-time as a carpenter and renovated the office for George Lucas and the others, when George Lucas started choosing actors, he asked him for help and gave other actors the right words during the audition. But in the process, director George Lucas saw the kind of acting talent he showed, and deduce Solow's greedy and arrogant character into the woods, and finally decided to let Harrison Ford play this role.
The role of Princess Leia was almost competed for by all the young actresses at the time, and what this role requires is that the actor has a noble temperament and the maturity that a leader needs. Carrie Fisher was the person most suitable for this role. Although she was still unknown at the time, her temperament made George Lucas think she was the best candidate.
The actor who plays Obi-Wan Kenobi is the famous British actor Sir Alex Guinness. He won the best actor Oscar for his starring role in the movie "The Bridge on the River Kwai" in 1958. Because of his leadership qualities, for Lucas, he is undoubtedly the most suitable person to play this role.
The actor who plays R2-D2 needs to be short, but has a lot of experience in acting. So the crew finally found the special actor Kenny Baker who was less than one meter tall. He has a wealth of performance experience, and at the same time has enough physical strength to complete various actions in the metal shell of the robot. The actor playing C-3PO is British actor Anthony Daniels. He was trained in pantomime performance and vividly played the robot C-3PO as one of the most popular characters in "Star Wars".
As the main supporting role in the film, it is also a difficult process to find an actor to play Solo’s co-pilot, Chubacca. Peter Matthew is a two-meter British stuntman who turned out to be a hospital nurse. It is precisely because of his height that the deputy director who chose the actor has a fancy to him at first sight.
