Why did Obi-Wan look so old?
In “A New Hope,” Obi-Wan is about 57 years old, while in “Revenge of the Sith” he is about 38 years old. There are a few reasons why Obi-Wan looked so old in “A New Hope.”
The actor, Alec Guinness, who played Obi-Wan was born in 1914, which would put him at 62 years old when the filming of A New Hope began in March of 1976. The actor was playing a character that was 5 years younger than his is actually age.
Interestingly, there was no concern about Obi-Wan’s appearance until the prequel trilogy films were released and Ewan McGregor took on the role of Obi-Wan Kenobi.
In 2003, Revenge of the site started filming and at the time Ewan McGregor, playing Obi-Wan Kenobi was 32 years old. The character was 38.
With Alec Guinness being older than the character he was portraying, and Ewan McGregor being younger than the character we can see quite an age difference which would give the appearance of Obi-Wan looking quite old in A New Hope.
From a storyline standpoint we can explain how old Obi-Wan looks based on the following factors:
Living in a harsh desert environment is known to cause people to look weathered and older than they actually are. Obi-Wan Kenobi, who lived on the desert planet Tatoine for many years. Possibly, he had a rough time of it.
Obi-Wan lived a life as a hermit, which mean living simply and often going without some of the basic necessities and creature comforts most are accustomed to.
The guilt that Obi-Wan Kenobi carried with him after the death of Anakin Skywalker was likely the cause of the lines that creased his face and the gray in his hair.
