Rocks, a film supported and acted by a group of young, diverse women from London, has picked up five prizes at the British Independent Film Awards.

The film – which handpicked its cast of unknown female leads from secondary schools around London – won best British independent film at last night’s (February 18) virtual awards ceremony, and one of its stars, Kosar Ali, was named both best supporting actress and most promising newcomer.

D’Angelou Osei Kissiedu, who was just seven when he played little brother Emmanuel, was named best supporting actor, while Lucy Pardee won the best casting award.

Rocks is the story of a teenage girl (Bukky Bakray) who struggles to look after her younger brother when their single mum takes off one morning. Left with no choice but to fend for themselves, she turns to her ever-reliable school friends (led by Ali’s Sumaya) for help.

What follows is a raw and hopeful coming-of-age story, powered by a dynamic debut performance from Bakray.

Following her victory, Ali told the PA news agency the film had made her “understand myself as a person as well as an actor”.

She added: “Before this whole experience I never thought I would be who I am today, winning awards and even pursuing this acting career.”

Speaking previously to NME about the film, Bakrya said: “It’s often said that the Black mundane experience wouldn’t be interesting in this industry. In order for it to be a worthy Black experience it would have to be an insane struggle, something overdramatised for the audience to engage with. But the small stuff is what’s truly special.”

Other winners on the night included the supernatural thriller His House, which picked up four awards, and The Father, which earned three wins on the night including best actor for Sir Anthony Hopkins.

Riz Ahmed took home best debut screenwriter for Mogul Mowgli, and his short film The Long Goodbye was named best British short film.
