Of French, Luxembourgish and British decent, Marianne Bourg was born in Germany. After leaving Germany at age 5, she spent most of her life in Luxembourg where she graduated high school with a specialization in Literature and Foreign Languages. She first studied Business and Finance in France, then Drama and Classics at the University of Cambridge. She later traveled around Asia and settled down in Cambodia for three months where she worked in a non-profit organization in partnership with UNESCO.
Marianne Bourg started acting at the age of 12: first at her school's theater company and later joining Luxembourg's National Conservatory for Drama at age 15. After graduating high school she took acting classes at Cours Florent in Paris while attending university. Realizing very soon that her passion for acting was calling too strongly for her to pursue a career in business, she moved to Los Angeles and started a full-time acting career.
After completing her MFA in Acting for Film in 2013, Marianne wrote and produced two short films, Silent Voices and Lies Hidden in the Truth. She then made her feature film debut in the movie Wizardream with Malcolm McDowell and in Helicopter Mom where she worked along Nia Vardalos and Jason Dolley. More recently she starred in the feature film, Road Wars, directed by Mark Atkins and the Japanese movie, Gun Woman, by director Kurando Mitsutake. In early 2015, Marianne won Best Actress at CMF for her role in the movie Snake Eyes, and later that year she was invited to attend the Cannes Film Festival, where Snake Eyes was selected to be screened.
