Question: Who plays the character that took the sword out of the stone in once upon a time?

Knowledge 1: Excalibur
In Arthurian romance, a number of explanations are given for Arthur's possession of Excalibur. In Robert de Boron's Merlin, the first tale to mention the ``sword in the stone ''motif, Arthur obtained the British throne by pulling a sword from an anvil sitting atop a stone that appeared in a churchyard on Christmas Eve. In this account, the act could not be performed except by`` the true king,'' meaning the divinely appointed king or true heir of Uther Pendragon. This sword is thought by many to be the famous Excalibur, and its identity is made explicit in the later Prose Merlin, part of the Lancelot - Grail cycle. This version also appears in the 1938 Arthurian novel The Sword in the Stone by British author T.H. White, and the Disney adaptation. They both quote the line from Thomas Malory in the 15th century; ``Whoso Pulleth Out This Sword of this Stone and Anvil, is Rightwise King Born of all England ''. The challenge of drawing a sword from a stone also appears in the Arthurian legends of Galahad, whose achievement of the task indicates that he is destined to find the Holy Grail, [SEP] Knowledge 2: Liam Garrigan

Ideas for a Conan film were proposed as early as 1970; Pressman and associate producer Edward Summer began a concerted effort to get the film made in 1975. It took them two years to obtain the film rights, after which they recruited Schwarzenegger for the lead role and Oliver Stone to draft a script. Pressman lacked capital for the endeavor, and in 1979, after having his proposals for investments rejected by the major studios, he sold the project to Dino De Laurentiis. Milius was appointed as director and he rewrote Stone's script. The final screenplay integrated scenes from Howard's stories and from films such as Kwaidan and Seven Samurai. Filming took place in Spain over five months in the regions around Madrid and Almería. The sets, designed by Ron Cobb, were based on Dark Age cultures and Frank Frazetta's paintings of Conan. Milius eschewed optical effects, preferring to realize his ideas with mechanical constructs and optical illusions. Schwarzenegger performed most of his own stunts, and two types of swords, costing $10,000 each, were forged for his character. The editing process took over a year and several violent scenes were cut.
