missing title, mention ‘thrill-makers’ multiple times & two internet hits seem to suggest this is a castle film called ” Thrill-Makers “, also appears to be dated 1956, includes footage of Louella Gallagher throwing knives at children & yo-yo man, others seem unidentifiable

“Circus families: children rehearsing trapeze routines at home; mother does knife throwing at children. Bungee jumpers (“yo-yo man”). A water skier uses a kite to take to the air. Going over falls in a barrel. Trapeze artists at the Eiffel tower, hanging from helicopter, trick motorcycles.”
