The musical Irene opened in 1919 and was revived in 1973, starring Debbie Reynolds.
The basic story is the same as in this film, and similar to the 1926 film of the same name.
Irene O'Dare (Anna Neagle), on an errand for her employers, goes to the home of Mrs. Vincent (Billie Burke) and meets Don (Ray Milland), a friend of Mrs. Vincent's son Bob (Alan Marshal).
Don suggests that she try out as a model in the "Madame Lucy" dress shop. For good measure, he invests in the shop himself. However, Irene isn't sure she wants the job after the store manager makes a pass. Don fires the manager and puts in another one, Smith (Roland Young), who visits Irene at her home and asks her to work for him.
Irene is a smash hit as a model, and Smith assigns her the most beautiful gown to wear at Mrs. Vincent's charity ball. Unfortunately, some Irish stew wrecks it. Irene goes anyway, wearing a stunning blue gown that belonged to her mother, and knocks everyone's socks off.
A guest at the ball, Princess Minetti, believes Irene is related to one Lady O'Dare, and Irene doesn't correct her.
Smith decides Irene is perfect for a publicity campaign to put the dress shop on the map. He sets Irene up in a Park Avenue suite, passing her off as the niece of Lady O'Dare. This way, she will be invited to social functions and wear the shop's beautiful gowns.
When a jealous fellow model tells a newspaper columnist that Irene is really shanty Irish, all hell breaks loose.
This is a nice musical, and Anna Neagle is lovely. She was an enormous stage and screen star in Britain and even has a street named after her. She did musicals and drama up until 1985. For 15 years, she was in the top 10 of biggest British box office stars. In this she dances, sings, and acts beautifully and looks wonderful in all of the gowns.
Good cast, well directed, a pleasant musical, and a good chance to see Anna Neagle, a British treasure.
