Having done the Professional Program in screenwriting at UCLA's School of Theatre, Film and Television (TFT), Zarina in 2017 also completed the screenwriting bootcamp at the National Film and Television School (NFTS) in Beaconsfield, UK.

Preceding that, she had made a 3-minute documentary during a 4-day beginners' bootcamp in San Francisco on documentary film-making. Called 'The Lost Souls of San Francisco' it was one of the two selected from the bootcamp for uploading to YouTube, where it can be seen.

The docudrama 'Flat 13' which she then wrote, directed, produced and narrated on a shoestring - and which was edited by Steven Cholerton - was showcased at the jointly-hosted 2009 Durban International Festival (DIFF)/Berlin International Film Festival - where it was screened twice.

'Women of the Sun', an international organisation encouraging and promoting women film-makers in Africa, was later granted permission by ETV to screen the film at downtown Johannesburg's popular Market Theatre to a packed group of youth across SA's racial spectrum, who in the post-screening discussion admitted they'd previously known nothing about Flat 13 and the group of young freedom activists - that included Nelson Mandela, then a law student in his early twenties - who used to hang out at the flat, rented by the teenager Ahmed Kathrada, often dancing the night away as they debated the path to a future nonracial South Africa, while fearlessly defying apartheid's laws forbidding inter-racial social and political gatherings.

This group included young women and men who were to become leading artists, musicians, writers and politicians in SA, including Walter Sisulu, Nadine Gordimer, Ismail Meer, Ruth First, Sophie de Bruyn and Hugh Masekela, to name but a few.
