A gold-digging, or rather diamond-digging, "dumb" blonde, played by Marilyn Monroe, and her singing gal pal, played by the vivacious Jane Russell, provide mutual support on a love boat cruise, where they flirt with, and woo, eligible and preferably rich, men, in this musical comedy from the early 50's. The story is thin and nonsensical. But that's OK, because the film's strengths lie in its comedic script, its dazzling musical numbers, and the inclusion of the visually stunning M. Monroe, as Lorelei Lee.
Superficially, Lorelei "seems" like a not very bright "babe", especially in some of her comments. For example, she counsels Russell's character by saying: "I want you to find happiness --- and stop having fun". But there is a subtle quality about Lorelei that suggests that she may be smarter than she lets on. One wonders if Monroe, who was quite intelligent and bookish in real life, was really acting in this film, or just being herself.
While there are several lively, and memorable, musical numbers, they are all lead-ins to the lavish, eye-popping musical finale. On a stage adorned in garish colors (orange, pink, and black mostly), a breathtakingly glamorous Monroe belts out the popular song: "Diamonds Are A Girl's Best Friend". Her singing (partially dubbed) is not quite as credible as the performance of Carol Channing in the Broadway version. Still, the film's finale is a cinematic spectacle, a veritable feast for the eyes and ears. "Gentlemen Prefer Blondes" is not a heavy weight "message" film. It is instead a pleasant and entertaining bit of fluff, where the emphasis is on fun, music, and glamour.
