 Only about two or three process (visual effects) shots appear in the  entire film, early on when David Niven (I) (qv) and  Cantinflas (qv) are in the balloon and we see the looking out over  the Pyrenees. These shots were accomplished by animation cameraman  William Williams (II) (qv), who also worked on the process shots  for Alfred Hitchcock (I) (qv)s _Vertigo (1958)_ (qv).
