Curtain Up is a 1952 British comedy film directed by Ralph Smart and starring Robert Morley, Margaret Rutherford and Kay Kendall.

[4] In an English provincial town, Drossmouth, a second-rate repertory company assembles at the Theatre Royal on Monday morning to rehearse the following week's play, a melodrama titled Tarnished Gold.

Even experienced artists like Robert Morley and Margaret Rutherford, as director and writer respectively, have difficulty in holding the piece together.

"[7] The notice in The New York Times stated: "the provincial repertory company gets a gentle and mildly whacky going-over in Curtain Up, the British import that began a stand at the Sixtieth Street Trans-Lux on Saturday.

It has such assets as Robert Morley and Margaret Rutherford, who easily manage to be quite superior to the threadbare situations in which they are involved, and it has the glaring deficit of being static for lengthy periods.

Margaret Rutherford is in fine fettle as the persistent playwright, while Robert Morley gives a performance of polished petulance as the director of the down-at-heel stock company who insists on wholesale changes.
