Damon called the "bullshit shots" a waste of everyone's time.
"The deal was that if you wanted to shoot in one of his buildings, you had to write him in a part," said Damon.
"[Director] Martin Brest had to write something in Scent of a Woman - and the whole crew was in on it. You have to waste an hour of your day with a bullshit shot: Donald Trump walks in and Al Pacino's like, 'Hello, Mr. Trump!' - you had to call him by name - and then he exits.
"You waste a little time so that you can get the permit, and then you can cut the scene out. But I guess in Home Alone 2 they left it in."
Trump went on to get his own show as host of The Apprentice. We all know what happened next.
