The official Warren Commission investigation concluded that Kennedy was shot from behind after his motorcade passed the depository, where Oswald was an employee.
But the doctors questioned this based on his horrifying injuries and the fact the bullet appeared to enter the front of his head.
Dr Ronald Jones, a senior doctor at Parkland, asked: 'The issue in retrospect is if Oswald was in the sixth floor depository, how could he have been shot from the front then? And so was there more than assailant?'
Dr Joe Goldstrich, who was a fourth-year medical student at the time, asked: 'How could a gunshot from the rear peel the scalp from the front back?'
The Parkland doctors were gathered by producer Jacque Lueth in 2013 after research indicated some of them had seen what they thought was a bullet hole in the front of Kennedy's neck.
They also examined photos from Kennedy's autopsy, which they had never looked at as a group.
They all concluded that the images looked different to what they had seen in the Parkland trauma room.
This could mean that the President's body was tampered with.
The footage of the doctors' recollections was not released until now because Mr Lueth had wanted to interview Jim Jenkins, the only surviving member of the autopsy team.This was not possible until 2021.
She also wanted to speak with government medical pathologist Michael Baden and lawyer Robert Tannenbaum.
He was deputy counsel to the House of Representatives Select Committee on Assassinations, which investigated both Kennedy's killing and the assassination of Martin Luther King.
The new documentary was made by Barbara Shearer.
Dr Kenneth Salyer, who was then a first-year resident at the hospital and died in 2020, said: 'When I saw the autopsy pictures, I thought somebody had tampered with the whole thing and it made me very suspicious.'
Dr Lawrence Klein, a third-year medical student at the time, recalled his memories of being in the operating theatre where Kennedy was treated.
'Dr [Malcolm] Perry and Dr [Charles] Baxter had just walked into that room ahead of me,' he said.
'And Dr Perry was standing on the right side of the cart the Preisdent was lying on. Dr Baxter [was] on the left side.'
He added: 'It was a lie, they really didn't tell the truth about it.'
The Warren Commission concluded that Oswald fired there bullets from a Mannlicher-Carcano rifle.
One bullet missed and is believed to have hit a sign.
The second - the so-called 'magic' bullet - hit Kennedy near the base of the back his neck.
The commission concluded that it then passed into Texas governor John Connally, who was sitting in front of the President and First Lady Jackie Kennedy with his wife Nellie.
Connally was injured in the back, chest, wrist and thigh.
The magic bullet theory made sense because the inquiry concluded that Oswald would not have been able to reload his weapon in time to shoot again.
The third bullet hit President Kennedy in the head.
A bullet - believed to be the one that had killed the President - was later found next to Governor Connally on his hospital stretcher and was assumed to have come from his body.
But theories that a second shooter was involved have persisted since the shocking killing.

But theories that a second shooter was involved have persisted since the shocking killing.
The second shooter theory was given further credence last month when one of Kennedy's bodyguards, Paul Landis, spoke to the Mail.
He had previously revealed that he found a bullet on the back of the presidential limousine and placed it next to the President on his stretcher.
He believed that in the chaotic aftermath of the shooting it got moved.
If the bullet found by Landis had not hit the governor but was the one found on his stretcher, then it raises questions about how he came to be shot.
Some witnesses had said that they heard shots from the 'grassy knoll', which was made famous in Oliver Stone's film JFK.
Recalling the moment the President was shot, Landis told the Mail: 'He was leaning slightly to his left, towards Mrs Kennedy, and I thought he was turning around to see where the noise came from.
'I didn't realise he had been hit by a bullet at that time.
'I heard the second shot. From my position, standing on the running board of the follow-up car, I didn't see any reaction in the President's car, so I thought that shot had missed.'
He added: 'I heard the third shot and I saw the President's head explode in a mist of blood and flesh and brain matter — and I ducked to avoid getting splattered.
'The third shot came fairly quickly after the second... and then we raced to Parkland Memorial Hospital.'
After Kennedy was confirmed dead, he was flown back to Washington DC aboard Air Force One.
Vice President Lyndon Johnson was sworn in as the new President on the flight.
Mrs Kennedy, who was still wearing the pink outfit that was stained with her husband's blood, was present.
When asked if she wanted to change her clothes, she refused and said: 'Let them see what they have done.'
The Staff: I posted only part of what this is and has been said. Maybe the truth will come out some day
