The first UK trailer for the highly anticipated Greta Thunberg documentary has been released.

I Am Greta takes a behind-the-scenes look at the teen Swedish climate activist, whose school strike in 2018 launched an entire global climate movement.

The film, which recently debuted as part of the Venice Film Festival earlier this month, arrives to the UK and Irish cinemas in mid-October.

Filmmaker Nathan Grossman and producers Cecilia Nessen (Bergman: A Year in the Life) and Fredrik Heinig (Midsommar), compiled the film, which features previously unseen footage that Traces Thunberg’s journey from a school student to the “voice of a generation”. It culminates in her trip across the Atlantic (in a zero emission sailing boat) to deliver her now-famous speech before the UN.

Last month, the 17-year-old announced her return to school after taking a year to travel the world with her climate activism. Her efforts have seen some groundbreaking change. The “Greta effect”, as it has been dubbed, has seen an increase in online activism among young people. She also won a Right Livelihood Award (AKA the “alternative Nobel Prize”), was named TIME’s Person Of The Year, had a beetle named after her, and a poem written for her by Patti Smith for her birthday.

I Am Greta is out in cinemas on October 16
