THE UGLY DUCKLING (1959):

Henry Jekyll (Bernard Bresslaw) is a bungling, awkward and socially inept buffoon working in his brother’s pharmacy.
One day he discovers an old formula created by his great-great-grandfather which claims to turn 'a man of timid disposition into a bold,
fearless dragon'. He eagerly mixes the formula, takes one drink, and is transformed into the suave, dashing and self-confident Teddy Hyde.

Teddy immediately becomes a darling of society and a big hit with the ladies. However he also craves the thrill of becoming a master criminal, and recruits a gang of expert crooks to join him in carrying out a series of daring and ambitious jewel robberies.
