In a recent GQ video interview, Ewan McGregor explained that portraying Obi-Wan Kenobi in the Disney+ series was easier than in the prequels. McGregor explained that since Obi-Wan is very broken after the events of Star Wars. Episode III: Revenge of the Sith, it was easier to fully understand the character. He said, “Playing him… is easier in a way, because I think the broken Obi-Wan Kenobi, the lonely, lonely character we meet at the beginning of the series, is a little closer to Alec Guinness’s Obi. – Wan Kenobi, not my… asshole, General Kenobi runs on lizards and stuff.
McGregor continued that he “loved it a lot” as he often thinks of Guinness’s portrayal of the character as a benchmark for what he tries to do with his version in order to continue the legacy. On Obi-Wan Kenobi, McGregor noted that the broken aspect of the character made him “feel a lot closer to himself”. [Alec Guinness].”
This isn’t the first time McGregor has mentioned that the image of Guinness influences what he does with the character (via StarWarsNews.net). He also mentioned his openness to the show’s second season (via Diversity), so hopefully we’ll see McGregor getting closer and closer to old Ben Kenobi if that ends up happening.
