SPARTACUS

Directed by Stanley Kubrick at 1960.
Peter Ellenshaw was hired by Universal to paint convincing mattes for the movie, even though there are some matte paintings from Russell Lawson who was  head of the matte department at Universal during that time.
 

That is the impressive  view of Rome painted by Peter Ellenshaw

Other views of Rome.

The quality of the pictures is not very good , but that's all I've  got from my VHS.
