Second-billed Marilyn Monroe is the blonde in question in this second film version of Gentlemen Prefer Blondes: Miss Lorelei Lee, whose philosophy is diamonds are a girls best friend. Together with her best human friend Dorothy (top-billed Jane Russell), showgirl Lorelei embarks upon a boat trip to Paris, where she intends to marry millionaire Gus Esmond (Tommy Noonan). En route, the girls are bedeviled by private detective Malone (Elliot Reid), hired by Esmonds father (Taylor Holmes) to make certain that Lorelei isnt just another gold-digger. When Dorothy falls in love with the poverty-stricken Malone, Lorelei decides to find her pal a wealthier potential husband, and thats how she gets mixed up with flirtatious diamond merchant Sir Francis Beekman (Charles Coburn) and precocious youngster Henry Spofford III (George Foghorn Winslow). Most of the Leo Robin-Jule Styne songs from the Broadway show remain intact, including Marilyn Monroes rendition of Diamonds are a Girls Best Friend, a production number later imitated by pop icon Madonna. ~ Hal Erickson, All Movie Guide
