I, Tonya (2017) 15 ◆

10PM, BBC4 ★★★★

The story of US figure skater Tonya Harding, told in this blackly comic mock documentary, should have been a ragsto-riches fairytale, but instead became a horror story. Poor and trashy, but extremely talented, Tonya (Margot Robbie, below) was pushed hard to succeed, and was surrounded by a bad crowd.
