Hanser is initially a stage and screen actress, born and raised in the city Utrecht, The Netherlands. Both her parents were born in Indonesia and moved to The Netherlands. They are part of the so-called Indo-European community, a heritage from the colonisation of Indonesia, formerly known as the Dutch East Indies.
At an early age, she already had a love for movies and says she learned English by "simply watching a lot of TV". The acting bug only kicked in at a much later age and she also developed a passion for writing. She went off to pursue an academic career before giving in to acting and studied International Business Management at The Hague University (BSc) and Anthropology and Journalism (MA) at the renowned Leiden
University. Surviving college through jobs in modelling and hospitality, she says that studying gave her the opportunity to travel the world, and as a result she speaks several languages including Spanish, Portuguese, German and French, in addition to her native Dutch and English.
She started growing more interest in acting and after several small-scale Dutch film projects like "Poolshoogte" (2014) she moved to London to train at the prestigious Drama Centre to obtain her third master degree in screen acting (MA). During this period, she also joined theatre company People's Co. as an in-house cast member and featured in one of their biggest West End productions Shakespeare's "A Midsummer Nights Dream" (2019) taking on the role of fairy queen Titania at the Southwark Playhouse. She also performed on stage and toured around the UK with the Extreme Improv Comedy Club. It was around this time that she also became passionate about Flamenco dance which got her a part in the documentary "Andalusia" (2018).
After being featured in the movie "Before You Were Born" (2017) she also started training in filmmaking and screenwriting and soon co-wrote and produced projects like "Fallen from Grace" (2019). The horror film projects including Panic (2019) and Tormented (2019) became successful on London's film festival scene and praised by the Raindance Film Festival. Being active in the martial arts and known for being a physical actress with stage combat and stunt performance background, Hanser was cast as the lead in the TV-series pilot "Parasitus" (2019) and the feature film "Blade of the Assassin" (2021) directed by Jopia Productions.
Hanser always believed there should be better roles for women, other than the “desperate housewife”, “promiscuous gangster lover” or “eternally-suffering mother”. With a suitcase full of scripts, she picked up the camera and started shooting films herself. The only way for her to express her cinematic visions and to give voice to stories about strong women. “A Tribute to Frida” is one of the first experimental shorts she shares with the world and was shot, edited, performed and written by Hanser herself.
