Ever heard of Columbia Pictures? It is a really famous American film studio.
Yes, I have heard of it but do not know much about it.  What movies  have they produced?
I'm not too sure, but I know some stars that became big from this studio, like Rosalind Russell and Glenn Ford.
I have not heard of either Rosalind Russell or Glenn Ford I don't believe, what movies/roles have they played?
I'm not sure of exact movies, but Glenn Ford is best at playing ordinary men in unusual circumstances.
Ok - anyone else that worked with Columbia PIctures that I might know?
One other that became a major star is William Holden.
Yeah, don't recognize his name either - perhaps I'd recognize any movies that he was in?
Well he won an Academy Award for Best Actor for the film Stalag 17.
