If it doesn't agree with the Report....just ignore it 
Some parts of that film don't agree with or report what the witnesses originally said.
James L. Simmons affidavit (March 19, 1964):
SIMMONS advised that it was his opinion the shots
came from the direction of the Texas School Book
Depository Building.
SIMMONS said he thought he saw exhaust fumes of
smoke near the embankment in front of the Texas
School Book Depository Building.
James L. Simmons at the Shaw Trial:
I was facing this way and the sound appeared to
come from this general direction over along here,
and there is a row of trees along the fence and
towards the end of the fence there is a small
building and just this side of it a few feet is
where I saw the smoke.
Simmons locates the "smoke" near the pergola shelter.
Sam Holland is telling Lane/Blake the third shot came from behind the fence. But Holland originally said" "But the puff of smoke I saw definitely came from behind the arcade through the trees." and testified:
Mr. HOLLAND - There was a shot, a report, I don't know whether it was a shot. I can't say
that. And a puff of smoke came out about 6 or 8 feet above the ground right out from under
those trees. And at just about this location from where I was standing you could see that
puff of smoke, like someone had thrown a firecracker, or something out."
In the film, Holland leads Lane/Blake to the inside corner of the wooden fence where "we saw the smoke and heard the shot". But that's not he first ran to.
Mr. STERN - When you ran behind the picket fence after the shots were fired, did you
come near the area where the station wagon was parked?
Mr. HOLLAND - Went up to behind the arcade as far as you could go.
Mr. STERN - So, you would have passed where this station wagon was?
Mr. HOLLAND - Yes.
Holland thought it could have been a firecracker thrown out from the pergola, the first place he ran to after the shots.
I believe Simmons and Holland caught a momentary sight of the bottle-breaking at the retaining wall reported by Marilyn Sitzman, who said the bottle smashing was louder than the shots.
The Sitzman bottle-smashing wasn't widely-known until the 1990s. Simmons and Holland seem to tie some visual anomaly that occurred near the shelter, with Holland running there first.
