Maurice Ostrer (né Morris Ostravitch; 9 May 1896 – 3 December 1975) was a British film executive.
[3] Ostrer was born in Bow, London, to Jewish emigrants Nathan Ostravitch from Minsk and Fanny Schäfer from Loslau, Prussia.
According to writer Robert Murphy, "Maurice's subsequent disappearance from the film industry... makes it easy to dismiss him as a dilettante whose success owed more to luck than judgement.
The break-up of the partnership with [producer Ted] Black was unfortunate and Gainsborough became severely debilitated in terms of acting, writing and directing talent.
But of the ten films Maurice Ostrer was directly responsible for, seven were big box-office successes and his vision of an efficiently run studio dedicated to medium budget entertainment films with the emphasis on a particular genre was unique and it was to provide a model for Hammer a decade later.
