The London Film Festival finishes this Sunday with the European premiere of Ben Wheatley's 1970s-set shoot-em-up 'Free Fire' – but before then Leonardo DiCaprio will swoop into town on Saturday night to walk the red carpet for 'Before the Flood', a new documentary he's produced and which he appears in.
When DiCaprio isn't appearing in films like 'The Revenant' (which won him his first Best Actor Oscar earlier this year), the 'Titanic' star often uses his time to bang the drum for ecological causes. Back in 2007, he produced and presented 'The 11th Hour', a documentary about saving the planet, and now he's made 'Before the Flood'. The film looks at our addiction to fossil fuels and its effect on the environment and also retraces DiCaprio's own awakening to green issues.
Of course, its DiCaprio's star power, not the issues explored in the documentary, which have won 'Before the Flood' a gala slot at the London Film Festival. They wouldn't be laying out the red carpet if it was presented by David Attenborough. But surely that's the point? DiCaprio hopes that interest in him will awaken some of his many fans to the issues he cares about. But, until then, altogether now, 'LEEEEE-OOOO!'.
