Me and Orson Welles is a 2008 British-American period drama film directed by Richard Linklater and starring Zac Efron, Christian McKay, and Claire Danes. Based on Robert Kaplow's novel of the same name, the story, set in 1937 New York, tells of a teenager hired to perform in Orson Welles's groundbreaking stage adaptation of William Shakespeare's Julius Caesar. He becomes attracted to a career-driven production assistant. The film was shot in London and New York and on the Isle of Man in February, March and April 2008, and was released in the United States on November 25, 2009, and the United Kingdom on December 4, 2009.
Holly Gent Palmo and Vincent Palmo Jr. adapted the film's screenplay from Robert Kaplow's novel of the same name about a teenager (in reality, the 15-year-old Arthur Anderson, who played Lucius in Welles' production) involved in the founding of Orson Welles' Mercury Theatre. After receiving funding from CinemaNX, a production company backed by the Isle of Man film fund, and an offer from Framestore Features to co-finance the film, Richard Linklater came on board to direct Me and Orson Welles. Zac Efron signed on as the lead in early January 2008, claiming he decided to take the role of Richard Samuels because "It's a completely different project than I've ever done before," while Claire Danes joined the cast as the protagonist's love interest Sonja Jones in late January. In the theatre, Christian McKay had portrayed Orson Welles in the one-man play Rosebud: The Lives of Orson Welles at a number of venues, including the Edinburgh Festival and King's Head (London). He reprised the role in the U.S. at the 2007 "Brits Off Broadway" festival, where Linklater saw his performance and then cast McKay as Welles, retaining him over the subsequent objections of the project's producer. Me and Orson Welles underwent filming in the Isle of Man, Pinewood Studios, London and New York from February to April 2008. Filming in London commenced first in mid-February, before scenes in the Isle of Man were shot February 24-March 14, 2008, where filming locations included Gaiety Theatre and various other parts of Douglas. During filming in Douglas, Efron and Danes believe they sighted a ghost, or "supernatural" being, outside a window on set at Gaiety Theatre. Filming in Britain resumed in late March for six weeks at Pinewood Studios. Other locations included Crystal Palace Park, where a facade of New York's Mercury Theatre was set up for a scene. Actor James Tupper claimed that the best replica of an old New York theater was in England, while many of the actors who filled the company were from the Royal Shakespeare Company. The production crew only briefly visited New York; photographs were taken and footage shot to be added into the film as digital effects. Every exterior shot was filmed on a single street built at Pinewood Studios with a green screen at one end; different angles and slightly altered set designs were used between shots to make the street appear different each time.

WHo were some of the actors?

Answer the question at the end by quoting:

Sam Houston was the fifth son of Major Samuel Houston and Elizabeth Paxton. Houston's paternal ancestry is often traced to his great-great grandfather Sir John Houston, who built a family estate in Scotland in the late seventeenth century. His second son John Houston emigrated to Ulster, Ireland, during the Ulster plantation period. Under the system of primogeniture, he did not inherit the estate.
Houston's political reputation suffered further due to the publicity related to the trial for his assault of Stanbery. He left for Texas in December 1832 and was immediately swept up in the politics of what was still a part of the Mexican state of Coahuila, attending the Convention of 1833 as representative for Nacogdoches. Houston emerged as a supporter of William Harris Wharton and his brother, who promoted independence from Mexico. This was the more radical position of the American settlers and Tejanos in Texas. He also attended the Consultation of 1835, and the Texas Army commissioned him as Major General in November 1835. He negotiated a peace settlement with the Cherokee of East Texas in February 1836 to allay their fears about independence. Houston was selected as Commander-in-Chief at the convention to declare Texan independence in March 1836, and he signed the Texas Declaration of Independence on March 2, 1836, his 43rd birthday. Mexican soldiers killed almost all of those at the Alamo Mission at the end of a 13-day siege on March 6. On March 11, Houston joined what constituted his army at Gonzales: 374 poorly equipped, poorly trained, and poorly supplied recruits. Word of the defeat at the Alamo reached him and, while he waited for confirmation, he organized the recruits as the 1st Regiment Volunteer Army of Texas. On March 13, Houston retreated before the superior forces of Mexican General Antonio Lopez de Santa Anna, as he was short on rations. Heavy rain fell nearly every day, causing severe morale problems among the exposed troops struggling through the mud. He received additional troops near present-day La Grange, after four days' march, and continued east two days later with 600 men. At Goliad, Santa Anna ordered the execution of more than 400 volunteer Texas militia led by James Fannin, who had surrendered his forces on March 20. Houston's forces were joined by 130 more men on March 26 near present-day Columbus, and the next day he learned of the Fannin disaster. Houston continued his retreat eastward toward the Gulf coast, drawing criticism for his perceived lack of willingness to fight, and two companies refused to retreat further on March 29 while they were camped along the Brazos River. Houston decided to use the opportunity for rudimentary training and discipline of his force. On April 2, he organized the 2nd Regiment and received a battalion of regulars, and he ordered all troops along the Brazos to join the main army on April 11, approximately 1,500 men in all. He began crossing the Brazos on April 12. Santa Anna finally caught up with the Texans, but he had split his own army into three separate forces in an attempt to encircle Houston's forces. Houston surprised Santa Anna's forces during their afternoon siesta at the Battle of San Jacinto on April 21, 1836. The Texans won a decisive victory in less than 18 minutes, suffering few casualties, although Houston's ankle was shattered by a stray bullet. Santa Anna was badly beaten and forced to sign the Treaty of Velasco, granting Texas its independence. Houston stayed on briefly for negotiations, then returned to the United States for treatment of his ankle wound.
