Problem: Obi-Wan "Ben" Kenobi is a fictional character in the Star Wars franchise. Within the original trilogy he is portrayed by Alec Guinness, while in the prequel trilogy a younger version of the character is portrayed by Ewan McGregor. In the original trilogy, he is a mentor to Luke Skywalker, to whom he introduces the ways of the Jedi. In the prequel trilogy, he is a master and friend to Anakin Skywalker.

Obi-Wan Kenobi is introduced in the original Star Wars living as the hermit Ben Kenobi on the planet Tatooine. When Luke Skywalker and the droid C-3PO wander off in search of the lost droid R2-D2, Obi-Wan rescues them from a band of native Tusken Raiders. At Obi-Wan's home, R2-D2 plays a recording of Princess Leia saying that R2-D2 contains the plans for the Death Star, the Galactic Empire's superweapon. Leia asks him to deliver the droid and the plans safely to the planet Alderaan in order to help the Rebel Alliance. Obi-Wan reveals his true identity and explains that he is a Jedi Master, a member of an ancient group of warriors that were hunted down and exterminated by his apprentice Darth Vader, the apparent killer of Luke's father. He gives Luke his father's lightsaber and asks him to accompany him to Alderaan and take up Jedi training. Luke declines, but after finding that his uncle Owen and aunt Beru have been killed by Imperial troops, he agrees to go with Obi-Wan to Alderaan and to train as a Jedi. In the spaceport city Mos Eisley, Obi-Wan uses the Force to trick Imperial troops into letting them through a military checkpoint. They enter a local cantina and make a deal with two smugglers, Han Solo and Chewbacca, to fly them to Alderaan aboard their ship, the Millennium Falcon. During the journey, Obi-Wan begins instructing Luke in lightsaber combat. He suddenly becomes weak and tells Luke of "a great disturbance in the Force". Emerging from hyperspace, the party finds that Alderaan has been destroyed by the Empire, and the Falcon is attacked by an Imperial TIE Fighter. The trio chases the TIE fighter to the Death Star, and subsequently get caught in the space station's tractor beam. On board the Death Star, Obi-Wan shuts down the tractor beam, but Darth Vader confronts him and they engage in a lightsaber duel. Obi-Wan uses the duel to distract Vader as Luke, Leia, Han and Chewbacca escape to the Falcon. Although Vader strikes Obi-Wan down, his body mysteriously vanishes the moment he dies. At the climax of the film during the Rebel attack on the Death Star, Obi-Wan speaks to Luke through the Force to help him destroy the Imperial station. In The Empire Strikes Back, Obi-Wan Kenobi appears several times as a spirit through the Force. On the planet Hoth, he appears to instruct Luke to go to the planet Dagobah to find the exiled Jedi Master Yoda. Despite Yoda's skepticism, Obi-Wan convinces his old master to continue Luke's training. He appears later to beseech Luke not to leave Dagobah to try to rescue his friends on Cloud City, although Luke ignores this advice. In Return of the Jedi, Obi-Wan again appears to Luke after Yoda's death on Dagobah. Obi-Wan acknowledges that Darth Vader is indeed Luke's father, revealed by Vader himself in the previous film and confirmed by Yoda on his deathbed, and also reveals that Leia is Luke's twin sister. After the Rebels destroy the second Death Star and defeat the Empire, Obi-Wan appears at the celebration on Endor, alongside the spirits of Yoda and the redeemed Anakin Skywalker (Vader's former Jedi self).

Problem: Alba was born in Pomona, California, to Catherine Louisa (nee Jensen) and Mark David Alba. Her mother has Danish, Welsh, German, English, and French ancestry, while her paternal grandparents, who were born in California, were both the children of Mexican immigrants. She has a younger brother, Joshua. Her third cousin, once removed, is writer Gustavo Arellano.

Alba expressed an interest in acting from the age of five. In 1992, the 11-year-old Alba persuaded her mother to take her to an acting competition in Beverly Hills, where the grand prize was free acting classes. Alba won the grand prize, and took her first acting lessons. An agent signed Alba nine months later. Her first appearance on film was a small role in the 1994 feature Camp Nowhere as Gail. She was originally hired for two weeks but her role turned into a two-month job when one of the prominent actresses dropped out. Alba appeared in two national television commercials for Nintendo and J. C. Penney as a child. She was later featured in several independent films. She branched out into television in 1994 with a recurring role as the vain Jessica in three episodes of the Nickelodeon comedy series The Secret World of Alex Mack. She then performed the role of Maya in the first two seasons of the television series Flipper. Under the tutelage of her lifeguard mother, Alba learned to swim before she could walk, and she was a PADI-certified scuba diver, skills which were put to use on the show, which was filmed in Australia. In 1998, she appeared as Melissa Hauer in a first-season episode of the Steven Bochco crime-drama Brooklyn South, as Leanne in two episodes of Beverly Hills, 90210, and as Layla in an episode of Love Boat: The Next Wave. In 1999, she appeared in the Randy Quaid comedy feature P.U.N.K.S.. After Alba graduated from high school, she studied acting with William H. Macy and his wife, Felicity Huffman, at the Atlantic Theater Company, which was developed by Macy and Pulitzer Prize-winning playwright and film director, David Mamet. Alba rose to greater prominence in Hollywood in 1999 after appearing as a member of a snobby high school clique in the Drew Barrymore romantic comedy Never Been Kissed, and as the female lead in the 1999 comedy-horror film Idle Hands, opposite Devon Sawa.
