 While making  _"Bassie en Adriaan en het geheim van de schatkaart" (1986)_ (qv),  the part of De Baron was played by Aad van Toor (qv). But while he  changed clothes from De Baron to Adriaan or vice versa, he couldnt  direct. So the whole set stood still for that time. Thats why  Paul van Gorcum (qv) took over the part of De Baron.
