I'm in Love with a Wonderful Guy I'm in Love with a Wonderful Guy "A Wonderful Guy" is a show tune from the 1949 Rodgers and Hammerstein musical "South Pacific." It was first introduced by Mary Martin in the original Broadway production and sung by Mitzi Gaynor in the 1958 film adaptation. In the show, Nellie sings this song after being convinced that despite the racial differences between her and Emile, there is good in him. And so she is elated to be in love with him. Rodgers and Hammerstein were as inspired by Mary Martin's personality as they were by the character of Nellie Forbush to
South Pacific (musical) play together ("Dites-Moi"). Ensign Nellie Forbush, a naïve U.S. Navy nurse from Little Rock, Arkansas, has fallen in love with Emile de Becque, a middle-aged French plantation owner, though she has known him only briefly. Even though everyone else is worried about the outcome of the war, Nellie tells Emile that she is sure everything will turn out all right ("A Cockeyed Optimist"). Emile also loves Nellie, and each wonders if the other reciprocates those feelings ("Twin Soliloquies"). Emile expresses his love for Nellie, recalling how they met at the officers' club dance and instantly were attracted to each other
