Although Susan Strassberg has been unfairly compared to Katharine Hepburn from the original Morning Glory, it's not quite a fair comparison. Forgetting that there is no one like Hepburn, Strassberg does do a decent job with the material given in Stage Struck. The problem is that the story has been changed and not for the better.
Romance was added to this production and it weakens the basic story of a young girl who is so single minded in her determination to be a success in the theater. The characters played by Adolphe Menjou and Douglas Fairbanks, Jr. in Morning Glory are now played by Henry Fonda and Christopher Plummer. The producer and the playwright now engage in a rivalry for Strassberg which weakens the story.
In the original Morning Glory it's made clear from the beginning that Menjou is a love 'em and leave 'em type and he's really got no interest in Hepburn in that direction as he sees she's not the type. Pipe smoking Fairbanks after Hepburn makes good would like to get something going with her, but she's into her art first and for always.
But Fonda and Plummer have a civilized rivalry for Strassberg and the story is which one will she choose. That I'm not telling.
Stage Struck has some nice location shots of New York in the late Fifties, Broadway and the Greenwich Village area and a bit of Park Avenue. Joan Greenwood is here as the star who falters and allows Strassberg her big break. Greenwood's quirky personality that British films utilized so well is strangely missing here. Herbert Marshall is great as the older actor that C. Aubrey Smith played in Morning Glory.
Stage Struck is a nice film, but definitely a come down from Morning Glory.
