Marty McFly and Doc Brown head Back To The Future and crash land on Jimmy Kimmel's show

Michael J Fox and Christopher Lloyd crash landed in the middle of Jimmy Kimmel’s monologue as their Back To The Future alter egos Marty McFly and Dr Emmett Brown.

The time travelling duo received a standing ovation from the audience as they emerged from the iconic DeLorean on the set of Kimmel’s talk show.

Wearing his white laboratory overall, Brown exclaimed “Great Scott! According to my calculations this is the year 2015 Marty – the future.”

McFly – dressed in his trademark red padded body warmer, and yet to discover a pair of power-lace up ‘sneakers’ – assumed that all of the people watching must haver "got here in flying cars".

Failing to see what has been achieved since leaving Hill Valley in 1985, McFly asked: "If you don’t mind me asking – what the hell have you guys been doing for the last 30 years?"

Kimmel attempted to fill the pair in on the advancements since 1985.

He explained how selfies are used to “document important life events”, smart phones are used to send emojis, and croissant and doughnut hybrids - cronuts - are “delicious”.

Unimpressed McFly remarked: "It seems that 2015 kind of sucks."

Brown then left McFly to head back to 1985 - in an Uber - and repair the space time continuum to fix the future.

Despite his character feeling disappointed with the lack of hoverboards and flying cars, actor Fox was presented with the world’s first “living pair” of power-lace ups.

Nike gifted him the shoes to celebrate Back To The Future Day on Wednesday.
