Which of these film directors has directed the most films in the "Harry Potter" series?

David Yates (born 8 October 1963) is an English film director who has directed feature films, short films, and television productions. He is best known for directing the later four films in the "Harry Potter" series. His work on the "Harry Potter" series brought him critical and commercial success along with accolades, such as the British Academy Britannia Award for Excellence in Directing.

Chris Columbus was the director on "Harry Potter and the Philosopher's Stone", he also directed the second film, "Harry Potter and the Chamber of Secrets". Columbus was set to direct all entries in the series, but he did not want to return for the third film, "Harry Potter and the Prisoner of Azkaban", claiming he was "burned out". He moved to the position of producer, while Alfonso Cuarón was approached for the role of director.

Because Cuarón decided not to direct the fourth instalment, "Harry Potter and the Goblet of Fire", a new director had to be selected. Mike Newell was chosen to direct the film, but he declined to direct the next film, "Harry Potter and the Order of the Phoenix", which was given to David Yates, who also directed "Harry Potter and the Half-Blood Prince" and "Harry Potter and the Deathly Hallows (Part 1 and Part 2)", becoming the only director to helm more than one film since Chris Columbus.
