Petticoat Fever is a 1936 American comedy film directed by George Fitzmaurice and written by Harold Goldman.

The film stars Robert Montgomery, Myrna Loy, Reginald Owen, Winifred Shotter and Otto Yamaoka.

His near desperate fever is abated when aviator Sir James Felton's plane makes an emergency landing nearby and Dascom discovers that Jim's companion is the beautiful Irene Campion.

However, because she is fond of Jim, who once saved her life, she convinces Dascom to bring him back so that she can tell him face-to-face that she isn't going to marry him.

When he learns that his uncle, a duke, has died and left his title and entire estate to him, Dascom realizes why Clara suddenly showed up and rushes off to stop Irene and Jim.
