Marty McFly worries he might turn gay, in a previously unseen (and kind of offensive) deleted scene from ‘Back To The Future – Part 1’.

80’s iconic sci-fi family favourite, Back To The Future is celebrating it’s 30th anniversary – and with it, a whole bunch of deleted scenes have been included as special features on the limited edition re-release.

In one scene, Marty McFly (Michael J. Fox) expresses concern to Doc Brown (Christopher Lloyd) that flirting with his own mother in the past may have serious consequences when he returns to his own time… like, maybe he’ll turn gay?!

Doc replies, “Why shouldn’t you be happy?!”
