Grandfather help

[millofski]

Hi there,

Bit of a random question - I'm trying to find out more about my biological grandfather (my mum was adopted).  He was meant to have had a walk-on/extra part on the 1963 film Cleopatra & also the odd stage role in London.  Is there any (easy) way of finding out whether he was involved in the Cleopatra movie or finding out if he had any stage roles?

The names of minor roles are listed as well as the main cast, but no way of telling if roles even "more minor than minor" are listed.
