McLaglen claimed to have been born in Tunbridge Wells, Kent, although his birth certificate records Stepney in the East End of London as his true birthplace. His father, Andrew Charles Albert McClaglen, later a bishop of the Free Protestant Episcopal Church of England, moved the family to South Africa when McLaglen was a child. One of ten siblings, he had eight brothers and a sister. Four of his brothers also became actors: Arthur (1888-1972), an actor and sculptor, and Clifford (1892-1978), Cyril (1899-1987) and Kenneth (circa 1901-1979).

McLaglen was one of many Fox stars who had cameos in the musical Happy Days (1929). He was reunited with Edmund Lowe and Raoul Walsh in a sequel to What Price Glory?, The Cock-Eyed World (1929), which was another huge success at the box office.  McLaglen made a musical with Walsh, Hot for Paris (1930), then made On the Level (1930). A Devil with Women (1931) was a buddy comedy with Humphrey Bogart. He was borrowed by Paramount for Dishonored (1931), starring Marlene Dietrich and directed by Joseph von Sternberg. He was in Not Exactly Gentlemen (1931) and hada cameo in the short film The Stolen Jools (1931). McLaglen, Lowe and Walsh reunited for a second sequel to What Price Glory?, Women of All Nations (1931). He was in Annabelle's Affairs (1931), Wicked (1931), The Gay Caballero (1932), and Devil's Lottery (1923). McLaglen and Lowe went to Paramount for Guilty as Hell (1932).  Back at Fox he was in Rackety Rax (1932) then made a fourth What Price Glory? film with Lowe, Hot Pepper (1933). McLaglen starred in Laughing at Life (1933) and returned to Britain to make Dick Turpin (1933).  McLaglen starred opposite Boris Karloff's crazed religious fanatic in John Ford's The Lost Patrol (1934) at RKO, a picture about desperate soldiers gradually losing their minds fighting Arabs in the desert of what is now Iraq.  At Paramount, McLaglen and Lowe were in No More Women (1934) (a non-What Price Glory? film), then McLaglen made Wharf Angel (1934). He was one of many stars in Murder at the Vanities (1934).
