In the elaborate musical finale, Judy Garland is dancing with an uncredited Charles Walters, who would eventually become one of MGM's top directors and direct Judy herself in both Parade de printemps (1948) and La jolie fermière (1950).
This film was originally purchased by MGM in 1932 by Irving Thalberg to possibly star Marion Davies. It sat on the shelf until 1942, when it was announced as a non-musical vehicle for Lana Turner. After Turner dropped out due to a scheduling conflict, the film was re-tooled as a screwball comedy/musical for Judy Garland.
Judy Garland's naturally dark hair was lightened to a dark blond as a key part of her glamorous image change and transition into adult roles.
Actor Gil Stratton commented "MGM killed her, absolutely. All of us at Fou de girls (1943) were on layoff for a month - on full salary - while she was doing retakes on Lily Mars vedette (1943). Two pictures at once. And that wasn't the only time they did that to her."
