Other successful directors from this era are Wim Verstappen and Pim de la Parra, whose movies were more commercial than those of their colleagues in the 1960s. In his book "Van Fanfare tot Spetters", film historian Hans Schoots argues that the flourishing period of Dutch film lies between these two films, ending with the controversial "Spetters", after which the happy era that was the seventies was over, and a more down-to-earth approach to filmmaking kicked in. Indeed, after 1980, few Dutch films managed to bring crowds of millions to the cinemas, partly due to a decline in interest, partly due to home video systems which resulted in an overall drop in cinema attendance in the Netherlands.
