<P> After 16 months, and having gained his Equity card, Serkis joined a series of touring companies, including productions of: Bouncers opposite Hull Truck; Florizel in The Winter's Tale; and the fool in King Lear with director Max Stafford - Clark . In the early 1990s he settled in London, and took roles in Dogboy, the Royal Court Theatre's production of Mojo, Bill Sikes in a television film of Oliver Twist (1999) and Wilson Milam's production of Hurlyburly (1997) at the Queen's Theatre, Shaftesbury Avenue, with Rupert Graves and David Tennant . </P> <P> Like many British actors, Serkis made the move to television by appearing in small roles, such as Greville in an episode of The Darling Buds of May (1992). However, one of his first major starring roles was in the joint BBC / HBO production of Einstein and Eddington (2008). Serkis played Albert Einstein, following the development of his theory of relativity, while David Tennant played British scientist Sir Arthur Eddington . Serkis joined director Mike Leigh's ensemble for two film productions, and appeared in the romantic comedy Loop (1997) alongside Susannah York . </P> <P> Serkis first came to wide public notice for his performance as Sméagol / Gollum, in The Lord of the Rings film trilogy (2001--2003), for which he provided motion capture movements and voice for the CGI character . His work on The Lord of the Rings started a debate on the legitimacy of CGI - assisted acting . Some critics felt Serkis should have been nominated for the Academy Award for Best Supporting Actor, since his voice, body language, and facial expressions were used . There is the argument that his CGI actions were partially, or in some cases fully, animated without his movements, but the same is true for actors in a traditional film with CGI . Serkis appears briefly in live action as pre-Gollum Sméagol at the beginning of The Return of the King, and the CGI Gollum's facial characteristics are fundamentally based on Serkis' own . </P> <P> Serkis has done critically acclaimed motion capture work in several other films, including the title character in the 2005 version of King Kong (in which he also played the ship's cook in live action) and as Caesar in Rise of the Planet of the Apes (2011), Dawn of the Planet of the Apes (2014), and War for the Planet of the Apes (2017). He also worked with game developers Ninja Theory on the 2007 release Heavenly Sword, providing the motion capture and voice for King Bohan (the game's main villain). </P>
