Harry Alan Towers (1920-2009) was a British film producer and screenwriter who frequently used the pseudonym Peter Welbeck for the latter role.
Following his service in the RAF during World War II, he started a company called Towers of London, which sold syndicated radio programs around the world. Among the titles he handled were The Black Museum and The Lives of Harry Lime, both starring Orson Welles. In the 1950s, he moved to television, where he regularly produced shows for ITV. He switched to working in film in the 1960s, where he produced many book adaptations. Among his more frequently employed source authors were Sax Rohmer and Agatha Christie (including three separate adaptations of And Then There Were None).
He was married to actress Maria Rohm, whom he often had cast in his movies.
