By October 1964, Garner had formed his own independent film production company, Cherokee Productions. He next starred in the Cherokee co-production, Norman Jewison's romantic comedy The Art of Love (1965) with Dick Van Dyke and Elke Sommer. The Westerns Duel at Diablo (1966) with Sidney Poitier and Hour of the Gun (1967) with Garner as Wyatt Earp and Jason Robards Jr. as Doc Holliday followed, as well as the comedy A Man Could Get Killed (1966) with Melina Mercouri and Tony Franciosa. Grand Prix (1966) with Eva Marie Saint and Yves Montand, directed by John Frankenheimer and co-produced through Garner's Cherokee Productions, left Garner with a fascination for car racing that he often explored by actually racing during the ensuing years. The expensive Cinerama epic by MGM did not fare as well as expected at the box office and, together with the poor performance of his last six films, he was blamed for the movie not doing better, which damaged Garner's theatrical film career.
