You've Been Trumped will get a special screening at the IFC Centre in New York on 7 July.
Last week, during his visit to the golf resort in Aberdeenshire, Mr Trump dismissed the documentary. He told journalists: "I haven't seen it. I heard it got some bad reviews. People told me it was boring."
But director Anthony Baxter immediately announced plans to take the film to New York "to hold Trump to account for his actions - in the court of public opinion." Within hours of the appeal going online, half the $4,000 (2,500) target had been reached, he said yesterday.
Mr Baxter, who leaves Aberdeen for New York tomorrow, added: "While Mr Trump may be used to getting special treatment, we think he should watch the film in a cinema like everyone else."
