She was educated at Street Monica"s, Skipton, Yorkshire, and at the Convent of the Sacred Heart School in Roehampton.
She was the eldest of four sisters (she also had an elder step-sister, Isabel Peacock, who later appeared in American films as Isabel Daintry). She adopted the professional name Mary Murillo after being compared in looks to a Murillo painting of the Madonna. In 1908 she traveled to America with her step-sister to start a stage career and in February 1909 made her debut in the chorus of the Broadway musical comedy Havana.
She toured the United States, finding only small parts until 1913, when she started sending scenarios to film companies.
Other commissions followed, and the first film known to be credited to her is A Strand of Blond Hair (1914), a Vitagraph comedy short starring John Bunny and Flora Finch. She wrote five melodramas for Theda Bara during the 1910s popularity of vamp films.
She also wrote for Bara"s Fox rival Valeska Suratt. Murillo served as screenwriter for Fox Film from 1916–1917, then joining Norma Talmadge Productions in 1919.
She returned to the United Kingdom in 1923 to work for Stoll Film Studios.
She wrote the script for the hit French sound film Accusée, levez-vous! She later worked for J. Arthur Rank, 1st Baron Rank"s Religious Films Limited.
