Lloyd Benedict Nolan (August 11, 1902 – September 27, 1985) was an American film and television actor. Among his many roles, Nolan is remembered for originating the role of private investigator Michael Shayne in a series of 1940s B movies. His obituary in the Los Angeles Times contained the evaluation, "Nolan was to both critics and audiences the veteran actor who works often and well regardless of his material." Although Nolan's acting was often praised by critics, he was, for the most part, relegated to B pictures. Despite this, Nolan co-starred with a number of well-known actresses, among them Mae West, Dorothy McGuire, and former Metropolitan Opera mezzo-soprano Gladys Swarthout. Under contract to Paramount and 20th Century-Fox studios, he essayed starring roles in the late 1930s and early-to-mid 1940s and appeared as the title character in the Michael Shayne detective series. Raymond Chandler's novel, The High Window, was adapted from a Philip Marlowe adventure for the seventh film in the Michael Shayne series, Time to Kill (1942); the film was remade five years later as The Brasher Doubloon, truer to Chandler's original story, with George Montgomery as Marlowe. 

Most of Nolan's films were light entertainment with an emphasis on action. His most famous include Atlantic Adventure, costarring Nancy Carroll; Ebb Tide; Wells Fargo; Every Day's a Holiday, starring Mae West; Bataan; and A Tree Grows in Brooklyn, with Dorothy McGuire and James Dunn. He also gave a strong performance in the 1957 film, Peyton Place, with Lana Turner. Nolan also contributed solid and key character parts in numerous other films. One, The House on 92nd Street, was a startling revelation to audiences in 1945. It was a conflation of several true incidents of attempted sabotage by the Nazi regime (incidents which the FBI was able to thwart during World War II), and many scenes were filmed on location in New York City, unusual at the time. Nolan portrayed FBI Agent Briggs, and actual FBI employees interacted with Nolan throughout the film; he reprised the role in a subsequent 1948 movie, The Street with No Name. One of the last of his many military roles was playing an admiral at the start of what proved to be Howard Hughes' favorite film, Ice Station Zebra.
