Green Book is a 2018 American biographical comedy-drama film directed by Peter Farrelly. Starring Viggo Mortensen and Mahershala Ali, the film is inspired by the true story of a 1962 tour of the Deep South by African American pianist Don Shirley and Italian American bouncer and later actor Frank "Tony Lip" Vallelonga, who served as Shirley's driver and bodyguard. Written by Farrelly alongside Lip's son Nick Vallelonga and Brian Hayes Currie, the film is based on interviews with Lip and Shirley, as well as letters Lip wrote to his wife. It is named after The Negro Motorist Green Book, a guide book for African American travelers founded by Victor Hugo Green in 1936 and published until 1966.
