Anthony Walters as Tim Crachit

 

 I just happened upon this picture of Anthony Walters as "Tiny Tim" Crachit from George Scott's Carol today. As the picture shows he was suitably pathetic for the role. 

Kim Downer and George C. Scott

 

Here is a post I found about an actor named Kim Downer who was in George Scott's Christmas Carol, I hadn't heard of him, but it looks like he could of played Fred or even Bob Crachit. Those roles were played by Roger Rees and David Warner respectively. This guy was an extra, who fondly recalled having met George C. Scott.
