Writer Andrew Katsis...Take a look at actor Marlon Brando in Mankiewicz's 1955 "Guys and Dolls..."

Guys and Dolls (1955)
"Figuring weight for age, all dolls are the same",
Nathan Detroit (Frank Sinatra) is the manager of the New York'slongest- established floating craps game, and he needs $1000 to securea new location. Confident of his odds, he bets the city'shighest-roller, Sky Masterson (Marlon Brando), that he can't woouptight missionary Sarah Brown (Jean Simmons).

'Guys and Dolls (1955)'is such a great musical because it deftly blends the contrasting stylesof film and stage. During a dazzling opening sequence, crowds ofpedestrians move in rhythm, stopping and starting as though respondingto backstage cues. Even the walking movements themselves are stylizedand angular, halfway between a walk and a dance.

Mankiewicz's New YorkCity is a glittering flurry of art deco colour and movement, a fantasyworld so completely removed from reality that even the business ofunderground gambling and criminal thuggery seems perfectly genial As I write this review, I've just received word that Jean Simmons haspassed away, age 80. This, unbelievably, was the first time I'd seenher in a film, yet she dazzled me from the beginning. Her idealisticand sexually-repressed Sarah comes out of her shell following analcohol binge in Havana, letting loose with an adorably playfulrendition of "If I Were A Bell."

Even though both Simmons and Brandowere non-singers, producer Sam Goldwyn decided not to dub their vocals...
...contending that "maybe you don't sound so good, but at least it's you."

Despite Goldwyn's backhanded confidence, the pair both do well to carry-entire musical numbers themselves. Simmons suggests the same child-like-liveliness that Audrey Hepburn might have brought to the role, and Brando exudes such self-assurance and charisma that it doesn't matter that his singing voice isn't quite there.
