Great Scott! Back to the Future Day on ITV2 sees all three time-travelling films aired in a celebration of the cult classics. Slap bang in the middle of this birthday bash is a one off celebratory special – Keith Lemon’s Back t’Future Tribute. It’s been 30 years since Marty McFly stepped into Doc Brown's time travelling DeLorean and ITV2 is celebrating in style. Back to the Future Day on 21 October 2015 is the date inventor Doc Brown and Marty journey to in Back to the Future II - to a world of flying cars and self-tying sneakers, instant pizza and faxes in every room. From 4.30pm, ITV2 will air all three films, plus at 9pm Back to the Future’s biggest fan, Keith Lemon, is creating his very own celebratory one off special to mark the occasion - Keith Lemon’s Back t'Future Tribute. So rev your engines up to 88 miles an hour and get your flux capacitor’s ready for a stellar trip through time.
