At 16 Malmgren intended to become a priest, but was dissuaded by his father. Instead in 1935 he began training as an actor with Julia Hakanson of the Svenska Teatern, and the following year as a dancer with Sven Trop, Ballet Master of the Royal Opera in Stockholm. In 1938 he went to Berlin to train with Eugenie Edwardova, former character dancer with
Pavlova, and with Trude Engelhardt of the
Mary Wigman company. While still in training he gave solo recitals throughout Sweden, followed in 1939-40 by solo recitals in Stockholm, Berlin, Warsaw and Paris where he began studying with Mme Preobrajenska. He was awarded the Gold medal at the
Concours de la Danse in Brussels in 1939 and was spotted by
Kurt Jooss who invited him to join Ballets Jooss based at
Dartington Hall. It was here that he first met
Rudolf Laban with whom he later collaborated in developing his theory of Movement Psychology. During the war he toured as a soloist with Ballets Jooss throughout the British Isles, Ireland, Canada, North and South America. He left the company in Buenos Ayres and spent the rest of the war period in Brazil, partnering the ballerina
Nini Theilade in solo recitals and opening a movement school in Rio de Janeiro. He returned to Europe in 1947 to give recitals in Sweden and Finland with Nini Theilade. In 1948 he was invited to join the International Ballet Company as premier danseur, and continued his training with Judith Espinosa in London, and Mmes Preobrajenska and Egorova in Paris. He appeared as 'the Baron' in
Gaite Parisienne opposite the choreographer
Massine, in his old role. A season at Teatro Municipal in Rio de Janeiro with Tatiana Leskova in 1950 was followed by tours throughout Britain and Europe. In 1954, following a serious injury he was forced to retire as a dancer, and began teaching classes at the International School of Ballet in London. The actor Harold Lang persuaded him to start giving movement classes in the Anna Northcote studio in West Street,
Covent Garden, and actors including
Sean Connery,
Diane Cilento,
Patricia Neal,
Gillian Lynne, Brian Bedford and
Anthony Hopkins together with directors
Tony Richardson, Bill Gaskill, Alexander Mackendrick and Seth Holt all attended. He worked privately with Sean Connery for a year who appeared in 'Anna Christie' in Oxford, and particularly as Dionysus in
Euripides's
the Bacchae before his first success as
James Bond. ==Teaching career==
