Thomas Douglas was born in 1972 in Lusaka, Zambia.
Due to his family background, he holds British, Swiss and German citizenship.

The Douglas family left Iran in 1979 due to the revolution and came to Munich, where Thomas had to learn German overnight. He grew up bilingual. (English and German)

After finishing drama school at the University of Hamburg he was hired by the experimental Theater am Neumarkt in Zurich and two years later he was invited to join the ensemble of the Theater Basel, one of the largest theaters in Europe. These 5 years were among his most formative working on protagonist characters in classical and modern plays with the finest directors in German Speaking Countries at this time.

His broad portfolio with over 80 theater - and more than 70 film productions in different, contrasting roles, characters and projects of all genres are a testimony to his desire not to be tied down, neither to a subject nor to a certain orientation. 

The collaborations with the experimental group CapriConnection around Anna Sophie Mahler led him on international guest performance tours from France to Germany to China.

In 2010 he won the Zurich Film Prize with the film ‘Zu Zweit – Together’ by Barbara Kulcsar and his wife Anina La Roche. This also laid the foundation for his film career. In 2012 he played aside Klaus Maria Brandauer and Sebastian Koch in the thriller ‘Manipulation’ by Alex Martin. 

Internationally he also became known to a wider audience with his performance as Ralph in the Netflix miniseries ‘The Billion Dollar Code’.

In 2022, Thomas took on a continuous part in the series "Save Me" produced by UFA Berlin for Amazon Prime as well as one of the lead roles for the international feature film production "Sew Torn" by Freddy Macdonald: Beck.
