What was the lady-like Dame Anna Neagle doing in something called Bad Girl -- or, as it was renamed in certain regions, Teenage Bad Girl? In point of fact, the film was originally and more tastefully titled My Teenage Daughter when Neagle signed on. Neagle plays Valerie Carr, the editor of a fiction magazine aimed at the youth market. Though she considers herself "hep" to the world of the young, she has no concept of what her own teenaged daughter, Janet (Sylvia Syms), is all about. When Janet falls into bad company, her mother does what she can to help. But Janet won't pay Mom any heed until her shenanigans land her in jail. Not at all exploitational, Bad Girl is constructed more along the lines of a 1940s "woman's picture" -- tears, renunciations, reconciliations. The film was produced and directed by Neagle's husband, Herbert Wilcox.
