In her documentaries, Polish filmmaker Hanna Polak approaches difficult subjects. Her Oscar-nominated film The Children of Leningradsky looks at the lives of children who live in or near Moscow's train station. Filmed over 14 years, Something Better to Come tells the story of Yula, who grew up living in Moscow's largest rubbish dump.

Polak is drawn to telling stories of vulnerable communities, hoping her films might start the process of change. She spoke to Journalism.co.uk at the Lviv Media Forum about the way she approaches filmmaking and shared some tips for those aspiring to become documentary makers.
