The film screening took place in connection with Cyril Ramaphosa's visit to the White House on Wednesday.
It was right in the middle of the meeting, with journalists present in the Oval Office, that Trump suddenly said:
Excuse me, turn off the light and show this, it's right behind you, referring to a video clip that began to roll on a screen behind him.
Trump has previously raised unfounded claims that whites in South Africa are being subjected to "genocide", and among other things, stated that the government in Pretoria is seizing land from whites.
You are allowing them to take the land, Trump claimed during the meeting between the two presidents.
No, no, no, no, Ramaphosa replied.
No one can take the land.
The South African government has consistently rejected the claims.
After the meeting, Ramaphosa says he is satisfied with the meeting.
It went very well, he says when leaving the White House, according to AFP.
