About me

Olivia Jannesson is a Swedish actor, voice artist and performance capture performer working across film, television, animation and video games.

Her work combines a grounded screen presence with strong physical and vocal range. She is particularly suited to intelligent, authoritative and physically demanding characters—from operatives and warriors to morally complex women whose strength is less obvious.

Olivia’s credits include Age of Empires, Bloodshore, The Heir of Time and Stranger Things: The Experience, alongside audiobook and commercial work from her broadcast-quality home studio. Her performance in Artificial Paradise received the Best Actor award in South Africa.

Having lived in seven countries, Olivia brings an international perspective and native fluency in both English and Swedish. Her physical practice includes MMA, boxing, fencing, horse riding, scuba diving and yoga, supported by experience in action and performance capture.

She is represented in the UK for screen, voice, performance capture and action work.

"What a find. Olivia understood the brief immediately - and delivered 3 voiceovers quickly and without fuss. She's professional, extremely talented (her voice is warm, human and so clear) - she was an absolute pleasure to work with - and I recommend her highly. I will work with her again for sure."
