Carl Theodor Dreyer preferred to work with non-actors, as he believed they offered a more reactive performance. In truth, it was because non-professionals did as he said without question or interpretation, which gave Dreyer greater control over the film. Jacques Tati and Pier Paolo Pasolini similarly used non-actors. With Tati it often blighted his films (see Traffic), while for Pasolini it brought something sublime (see The Gospel According to Saint Matthew).
For Dreyer, the use of non-actors in Vampyr (1932), added to the disorienting, dream-like quality, drawing the spectator into a strange and compelling, nightmare world.
