These Peter Ellenshaw Matte Shots  from Third Man on the Mountain 1959 Walt Disney. According to Ken Annakin – the film director – in his Autobiography that when the film had a first showing these shots were so realistic that members of the audience had to leave the cinema suffering with vertigo.  Just take a look at the pictures and you can imagine why when this was viewed on the big wide screen.

Peter Ellenshaw added Disney movie magic to the film, designing matte paintings for scenes like in the above two  with  dizzying downward shots that would have been impossible to capture with the film cameras.
