 when the Nautilus is doing battle against a pack of  Garfish, footage of missile tubes opening is lifted from  _Top o Nerae! (1988) (V)_ (qv). Also, stock footage of the ocean  waves beating against the sand from the Island episodes and the  explosion caused by the Tower of Babels energy beam in this series  ends up being used again in _"Shin seiki evangelion" (1995)_ (qv).
