The film opened at the Odeon Marble Arch cinema in London on 10 August 1951, and was one of the most popular films of the year in Britain.
The gurgling musical theme, "Guggle Glub Gurgle", that plays when Sidney Stratton’s apparatus is bubbling or when he is thinking about his invention is not made by musical instruments, but by laboratory equipment.
Jack Howarth as Receptionist at Corland Mill. Mandy Miller as Gladdie, little girl who sends a message for Stratton. A realisation hits and he exclaims, "I see!" With that he strides off, perhaps to try again elsewhere. Departing, he consults his chemistry notes. The next day, Stratton is dismissed from his job. Only Daphne Birnley, the mill-owner's daughter, and Bertha, a works labourer, have sympathy for his disappointment. The mob, realising the flaw in the process, rip pieces off his suit in triumph, until he is left standing in his shirt and underwear. As the crowd advances, his suit begins to fall apart as the chemical structure of the fibre breaks down with time. The climax sees Stratton running through the streets at night in his glowing white suit, pursued by both the managers and the employees. Going back to his rooms he is confronted by a woman who he thought was on his side, but suddenly realises that no-one wants his invention. The bosses negotiate with Daphne, the daughter of the owner of Birnley Mills, that she will trick Stratton into giving it all up and she asks £5000 for this, but when she meets Stratton she has a change of heart and encourages him to announce his invention to the press. Managers and workers each try to shut him away, but he escapes. The managers try to trick and bribe Stratton into signing away the rights to his invention but he refuses. Stratton is lauded as a genius until both management and the trade unions realise the consequence of his invention once consumers have purchased enough cloth, demand will drop precipitously and put the textile industry out of business. From this fabric, a suit is made-which is brilliant white because it cannot absorb dye and slightly luminous because it includes radioactive elements. Whilst working as a labourer at the Birnley Mills, he accidentally becomes an unpaid researcher and invents an incredibly strong fibre which repels dirt and never wears out.
Sidney ("Sid") Stratton, a brilliant young research chemist and former Cambridge scholarship recipient, has been dismissed from jobs at several textile mills in the north of England because of his demands for expensive facilities and his obsession with inventing an everlasting fibre.
