There have been many talented British filmmakers throughout history, and it can be difficult to choose the "biggest" or most influential. However, some British filmmakers who have made significant contributions to the industry and are considered to be among the most prominent are:
Sir Alfred Hitchcock, known as the "Master of Suspense," directed a number of classic films such as Psycho, Rear Window, Vertigo, and North by Northwest. He was one of the most successful and influential filmmakers of the 20th century.
Sir David Lean, a film director, producer, screenwriter and editor. His films such as The Bridge on the River Kwai, Lawrence of Arabia, and Doctor Zhivago were critically acclaimed and won multiple Academy Awards.
Sir Christopher Nolan, is a contemporary film-maker who directed and co-wrote the Dark Knight trilogy, Inception and Dunkirk. He has been nominated for eight Academy Awards and won one for Best Original Screenplay for Memento.
Mike Leigh, known for his realistic and often bleak character studies of contemporary working-class life and social issues in films such as Secrets & Lies, Life is Sweet, and Another Year.
Ken Loach, whose films often deal with social and political issues, has been known for his socially conscious films such as Kes, My Name Is Joe, and I, Daniel Blake, which won the Palme d'Or at the 2016 Cannes Film Festival.
Danny Boyle, known for his eclectic style, directed films such as Trainspotting, Slumdog Millionaire, and Steve Jobs, and has won an Academy Award for Best Director for Slumdog Millionaire.
