VIDEO : 'First Man'

"First Man" screenwriter Josh Singer explains why he believes the ending of the movie is accurate.
It comes right from the autobiography of Neil Armstrong that the movie is based on.
One of the most dramatic moments is at the end of the movie.
Apollo 11 has successfully landed on the moon.
Armstrong walks the lunar surface and comes across a dark crater.
He opens his hand to reveal a child-sized bracelet with the name of his daughter, Karen.
Karen had died of a brain tumor when she was two.
