Known as "One-Take Charlie" for his approach to acting that strove for spontaneity and energy, rather than perfection, Sinatra was an instinctive actor who was best at playing parts that mirrored his own personality. He continued to give strong and memorable performances in such films as Guys and Dolls (1955), The Joker Is Wild (1957) and Some Came Running (1958). In the late 1950s and 1960s Sinatra became somewhat prolific as a producer, turning out such films as A Hole in the Head (1959), Sergeants 3 (1962) and the very successful Robin and the 7 Hoods (1964). Lighter roles alongside "Rat Pack" buddies Dean Martin and Sammy Davis Jr. were lucrative, especially the famed Ocean's Eleven (1960). On the other hand, he alternated such projects with much more serious offerings, such as The Manchurian Candidate (1962), regarded by many critics as Sinatra's finest picture. He made his directorial debut with the World War II picture None But the Brave (1965), which was the first Japanese/American co-production. That same year Von Ryan's Express (1965) was a box office sensation. In 1967 Sinatra returned to familiar territory in Sidney J. Furie's The Naked Runner (1967), once again playing as assassin in his only film to be shot in the U.K. and Germany. That same year he starred as a private investigator in Tony Rome (1967), a role he reprised in the sequel, Lady in Cement (1968). He also starred with Lee Remick in The Detective (1968), a film daring for its time with its theme of murders involving rich and powerful homosexual men, and it was a major box-office success.
