He is portrayed in The Phantom Menace, Attack of the Clones and Revenge of the Sith by Ewan McGregor. In A New Hope, The Empire Strikes Back and Return of the Jedi, he is portrayed by Sir Alec Guinness.
Obi-Wan first appears in A New Hope, seemingly a mysterious hermit. He is revealed as a Jedi Master, who then tutors Luke Skywalker to use the Force. In the prequel films, he appears as a young Jedi, progressing from Jedi apprentice to Jedi master.
