The M23 is instantly recognisable to many people as the 'Marlboro'-liveried car that took James Hunt to the Drivers' World Championship in 1976. The intense rivalry between Hunt and Niki Lauda for the '76 World Championship is the subject of a forthcoming major Hollywood film, Rush, scheduled for release during 2013. The film is directed by Ron Howard (the man behind Apollo 13, The Da Vinci Code and Frost/Nixon), and the script for the film has been penned by British screenwriter Peter Morgan, whose credits include Frost/Nixon and The Queen. The McLaren M23 first appeared in 1973, and was McLaren's first World-Championship-winning car, winning two championships in 1974 in the hands of Emerson Fittipaldi, and in 1976 in the hands of James Hunt.
