In 1950, Weinstein began her film career in Paris having left the USA to avoid the rise of anticommunism, as typified by the House Un-American Activities Committee. In 1952, after settling in London, she established her own production company, Sapphire Films, financally aided by the American Communist Party. The company eventually made series for the British commercial ITV network via an arrangement with ITC's Lew Grade. Weinstein created and executive produced The Adventures of Robin Hood, starring Richard Greene. The first two series were syndicated by Official Films to American television stations; they also dwell on the theme of betrayal. Weinstein created the series with the intention of helping blacklisted American writers. She commissioned scripts by 22 Americans writers blacklisted after being identified as communists by HUAC, such as Waldo Salt, Ring Lardner Jr., Ian McLellan Hunter who all adopted pseudonyms, but were paid less than their usual fees. Weinstein instituted security measures to ensure that the writers' true identities remained secret. Louis Marks, one of the series' script editors later remarked: "Had even a hint of this leaked, the whole enterprise would have foundered". Sonia, Marks' wife who worked as Weinstein's assistant was told never to accept registered post in case it was a subpoena to appear at a HUAC hearing. The FBI considered Weinstein a "concealed Communist". It discovered by 1955, via an American embassy agent, that Sapphire Films was "influenced by the communists" but no action against the company is recorded. Director J. Edgar Hoover was aware the British press was usually against McCarthyism. The success of Robin Hood led Weinstein to create a further four television series, The Buccaneers, The Adventures of Sir Lancelot, Sword of Freedom and The Four Just Men. Sapphire Films ceased to function in late 1961 owing to financial problems caused by Weinstein's then husband, John Fisher. She returned to America in 1962. She organized a rally in Madison Square Garden to raise funds for the election of United States senators opposed to the Vietnam War.

She later produced Greased Lightning and Stir Crazy, both of which star comedian Richard Pryor. In 1982, she was awarded the Women in FilmCrystal Award for outstanding women who, through their endurance and the excellence of their work over their lifetime, have helped to expand the role of women within the entertainment industry. In 1984, she was named for the Liberty Hill FoundationUpton Sinclair Award in honor of her artistic and political accomplishments.
