Question: Who is best known for directing the "Doctor" series of films, Ralph Thomas or Rian Johnson?
Context: Ralph Philip Thomas MC (10 August 1915 – 17 March 2001) was an English film director, born in Hull, East Riding of Yorkshire.  He is perhaps best known for directing the "Doctor" series of films. Ralph Thomas "Tommy" Puett lll (born January 12, 1971) is an American actor, singer, dancer, and businessman.  He is best known for his role as Tyler Benchfield on "Life Goes On".  Tommy left the show in 1991.  Tommy is the older brother of former Kids Incorporated star Devyn Puett.  In high school Tommy was signed to Scotti Brothers Records.  Tommy released his only album "Life Goes On" in 1990.  That same year Tommy's only video album "Heart Attack" was released.  Devyn sang back up vocals on the album.  After releasing "Life Goes On" Tommy was cast as Ben in "Switchback" in 1997.  "Switchback" was Tommy's last acting role. Doctor in Distress is a 1963 British comedy film directed by Ralph Thomas and starring Dirk Bogarde, James Robertson Justice, and Samantha Eggar.  It's the fifth of the seven films in the "Doctor" series.  After a one-film absence, it marked the final return to the role of Simon Sparrow by Dirk Bogarde, and also the return (although in a different role) of Donald Houston.  The film uses some of the characters in Richard Gordon's "Doctor" novels, but is not based on any of the novels. Rian Craig Johnson (born December 17, 1973) is an American film director, screenwriter, editor, and actor.  He won the Special Jury Prize for Originality of Vision at the 2005 Sundance Film Festival with his debut feature film, "Brick".  Johnson directed "The Brothers Bloom" (2008) and "Looper" (2012), as well as three episodes of the AMC series "Breaking Bad" ("Fly", "Fifty-One", and "Ozymandias"). Some Girls Do is a 1969 British comedy spy film directed by Ralph Thomas.  It was the second of the revamped Bulldog Drummond films (following 1967's Deadlier Than the Male) starring Richard Johnson as Drummond, made following the success of the James Bond films of the 1960s. Nicholas Phipps (23 June 1913 – 11 April 1980) was a British actor and screenwriter who appeared in more than thirty films during a career that lasted between 1938 and 1970.  He was born in London in 1913.  He appeared mainly in British comedy films, often specialising in playing military figures.  He was also an occasional screenwriter, sometimes working on the script for films in which he acted.  Best known for his collaborations with Herbert Wilcox and Ralph Thomas, Phipps wrote some of the most popular British films of all time, including "Spring in Park Lane" (1948) and "Doctor in the House" (1954).  He retired from acting in 1970. Doctor at Sea is a 1955 British comedy film, directed by Ralph Thomas, produced by Betty E. Box, and based on Richard Gordon's novel by the same name.  This was the second of seven films in the "Doctor" series, following the hugely popular "Doctor in the House" from the previous year.  Once again, Richard Gordon participated in the screenwriting, together with Nicholas Phipps and Jack Davies, and once again Dirk Bogarde played the lead character Dr Simon Sparrow.  The cast also includes James Robertson Justice and Joan Sims from the first film, but this time playing different characters.  This was Brigitte Bardot's first English-speaking film. Jeremy Jack Thomas, CBE (born 26 July 1949) is a British film producer, founder and chairman of Recorded Picture Company.  He produced Bernardo Bertolucci's "The Last Emperor", which won the 1988 Academy Award for Best Picture.  In 2006 he received a European Film Award for Outstanding European Achievement in World Cinema.  His father was director Ralph Thomas (director of many of the "Doctor" films), while his uncle Gerald Thomas directed all of the films in the Carry on franchise. Doctor in Trouble is a 1970 British comedy film, the seventh and last film in the "Doctor" series.  It was directed by Ralph Thomas and stars Leslie Phillips as a doctor who gets accidentally trapped on an outgoing cruise ship while it begins a round the world trip.  The cast was rounded out by a number of British comedy actors including James Robertson Justice, Harry Secombe and Angela Scoular.  It was based on the story "Doctor on Toast" by Richard Gordon. Harrie Thomas Lindeberg (1879–1959) was an American architect, best known for designing country houses in the United States.  Among academic eclectic architects Lindeberg found a niche as "the American Lutyens" by working in a variety of popular styles while imparting a crisp modern stamp to his work.  He might best be compared to contemporary Art Deco and Streamline Moderne skyscraper architects such as Raymond Hood, Ely Jacques Kahn, and Ralph Thomas Walker.
