Which character did Sinatra play in Guys and Dolls? Frank Sinatra played Nathan Detroit. In the 1955 film adaptation, Nathan is a small-time New York gambler who organizes an illegal floating craps game while trying to raise a $1,000 security deposit for a gambling venue.

Nathan is also engaged to Miss Adelaide, a nightclub singer who has been waiting fourteen years for him to marry her. To solve his financial problems, he bets Sky Masterson that Sky cannot take missionary Sergeant Sarah Brown to dinner in Havana. That wager drives the film's central romantic and comic plot.

A common mix-up comes from Sinatra's co-star Marlon Brando. Brando played Sky Masterson, the gambler who accepts Nathan's challenge, while Vivian Blaine reprised her Broadway role as Adelaide and Jean Simmons played Sarah. Big Jule is a mobster, and Nicely-Nicely Johnson is another gambler, not Sinatra's character.

The casting was controversial because Nathan had been written for Sam Levene, who originated the role on Broadway. Sinatra's smoother interpretation differed sharply from Levene's more rumpled stage performance, but Nathan Detroit remains Sinatra's official character in the film.
