2015 is the year Marty McFly comes to the future, so what better time to take stock of the huge cultural impact the Back to the Future franchise has had? While we might not have hoverboards, flying cars, or a holographic Jaws 19 (yet, there's still time), the films have created a huge second-hand market for DeLoreans, made Nike Power Laces a real thing, and saw Queen Elizabeth Olympic Park turned into a 1950s Hill Valley by Secret Cinema. 

After a successful Kickstarter campaign back in 2013, the documentary Back in Time have returned to crowdfunding after the scale and ambition of the project has increased. Here's a trailer: 

You can tell the filmmakers are fans because, despite having great access to the stars of the film, they still took the time to interview Mayor Goldie Wilson (Donald Fullilove).
