Only one day of filming took place on The Heroine, on 14 April 1967,[2] in the opera house of Budapest, using arc lights for the last time in Welles' career.
During that day, Welles began to have serious doubts about the technical competence of the Hungarian film crew.
Consequently, Welles covertly left the country after just one day's filming, leaving his debts unpaid.
