The methods of pseudo-documentary have been sharply criticized in some cases, notably with the 1991 Oliver Stone film "JFK", which mixes fact with fiction to advance Stone's point that John F. Kennedy was the victim of a conspiracy. The film cuts confusingly between actual footage of alleged assassin Lee Harvey Oswald and staged images of actor Gary Oldman who is playing Oswald. The modern sequences are badly lit and they are artificially made grainy and scratched-looking so that they appear to be 1963-era 16 mm film. Stone uses the pseudo-documentary format to influence the viewer by presenting the conspiracy theory in a scientific and authoritative manner.
