 While this film was still in production, Philip Yordan (qv) and  his company (Security Pictures) had production designer and special  effects expert Eugène Lourié (qv) design and shoot special effects  footage for _Krakatoa, East of Java (1969)_ (qv) even though there  was no script. This footage would also be shot in large format for  Cinerama presentation. Those who were shown the early footage began  ignoring this film and asking when "Krakatoa" would be ready.
