Question: Which 2014 British biographical romantic drama film had an actor who also appeared in the 2008 film "Me and Orson Welles?"
Context: Christian Stuart McKay (born 30 December 1973) is an English stage and screen actor.  He is well known for his portrayal of Orson Welles in the 2008 film "Me and Orson Welles", which received international critical acclaim and was nominated for over two dozen awards including the BAFTA Award for Best Supporting Actor.  He also appeared in movies such as "Florence Foster Jenkins", "The Theory of Everything", "Tinker Tailor Soldier Spy" and "Rush". Citizen Kane is a 1941 American mystery drama film by Orson Welles, its producer, co-screenwriter, director and star.  The picture was Welles's first feature film.  Nominated for Academy Awards in nine categories, it won an Academy Award for Best Writing (Original Screenplay) by Herman J. Mankiewicz and Welles.  Considered by many critics, filmmakers, and fans to be the greatest film of all time, "Citizen Kane" was voted as such in five consecutive British Film Institute "Sight & Sound" polls of critics, until it was displaced by "Vertigo" in the 2012 poll.  It topped the American Film Institute's 100 Years ... 100 Movies list in 1998, as well as its 2007 update.  "Citizen Kane" is particularly praised for its cinematography, music, editing and narrative structure, which have been considered innovative and precedent-setting. "Raising Kane" is a 1971 book-length essay by American film critic Pauline Kael, in which she revived controversy over the authorship of the screenplay for the 1941 film "Citizen Kane".  Kael celebrated screenwriter Herman J. Mankiewicz, first-credited co-author of the screenplay, and denigrated the contributions of Orson Welles, who co-wrote, produced and directed the film, and performed the lead role.  The 50,000-word essay was written for "The Citizen Kane Book" (1971), as an extended introduction to the shooting script by Mankiewicz and Welles.  It first appeared in February 1971 in two consecutive issues of "The New Yorker" magazine.  In the ensuing controversy Welles was defended by colleagues, critics, biographers and scholars, but his reputation was damaged by its charges.  The essay was later discredited after Welles's contributions to the screenplay were documented and Kael's own scholarship was called into question. 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. A United Kingdom is a 2016 British biographical romantic drama film directed by Amma Asante and written by Guy Hibbert, based on the true-life romance between Sir Seretse Khama and his wife Ruth Williams Khama.  David Oyelowo and Rosamund Pike portray Seretse and Ruth, respectively. Edgar Barrier (March 4, 1907 – June 20, 1964) was an American actor who appeared on radio, stage, and screen.  In the 1930s he was a member of Orson Welles' Mercury Theatre and was one of several actors who played Simon Templar on "The Saint" radio show.  He also appeared in two films with Welles, "Macbeth" and "Journey into Fear".  Barrier also appeared in the 1938 Welles-directed short, "Too Much Johnson", which was long believed lost but was rediscovered in 2013. The Theory of Everything is a 2014 British biographical romantic drama film directed by James Marsh and adapted by Anthony McCarten from the memoir "Travelling to Infinity: My Life with Stephen" by Jane Wilde Hawking, which deals with her relationship with her ex-husband, theoretical physicist Stephen Hawking, his diagnosis of amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease or motor neurone disease), and his success in physics. Vienna (also known as Orson Welles' Vienna or Spying in Vienna) is a 1968 short film directed by Orson Welles.  It was originally produced as part of his abandoned television special, Orson's Bag, which was made for CBS; but in 1969, with the project close to completion, CBS withdrew their funding over Welles' long-running disputes with US authorities regarding his tax status.  The film remained uncompleted.  Despite its name, "Vienna" freely mixes footage shot in Vienna, Zagreb, and in a Los Angeles studio.  The 8-minute segment was restored by the Munich Film Museum in 1999. Return to Glennascaul, also known as Orson Welles' Ghost Story, is a 1951 short film starring Orson Welles.  It was written and directed by Hilton Edwards and produced by Micheál MacLiammóir for Dublin Gate Theatre Productions. Richard France (born May 5, 1938) is an American playwright, author, and film and drama critic.  He is a recognized authority on the stage work of American filmmaker Orson Welles.  His publication, "The Theatre of Orson Welles", which received a CHOICE Outstanding Academic Book Award in 1979, has been called "a landmark study" and has been translated into Japanese.  His 1990 companion volume, "Orson Welles on Shakespeare" has been praised by Welles critics and biographers.
