 The scene in which Lucy Gutteridge (qv) looks down from the  balcony onto the street to see hamsters and mice was in fact a  miniature from _Superman (1978)_ (qv). The Zucker Brothers and  Jim Abrahams (qv) stated in their DVD commentary that they found  it in the old Shepperton studios and thought it would be a great  idea to use it in somewhere in the movie.
