The screenwriter for Back to the Future Part II said the older, creepier, millionaire-hotel-mogul version of Biff Tannen was inspired by Donald Trump.
The character is named for studio executive Ned Tanen following an incident years earlier where Tanen reacted aggressively to a script being pitched by the film's writers Bob Gale and Robert Zemeckis. Tanen accused the two of attempting to produce an antisemitic work with their 1978 film I Wanna Hold Your Hand.Drafts of "Back to the Future" show Biff with the middle initial of "H", but this detail was omitted in further revisions.
As the films' important October 2015 date approached, commentators began noting the similarities between the older version of Biff Tannen and then presidential candidate Donald Trump. When the comparison was brought to Gale's attention in an interview, he stated that elements of Tannen's personality were actually based on Trump, who was already well known in the late 1980s for his work in real estate and tabloid controversies.
