Marek we are thinking along the same lines. You beat me to it.
I was just going to do the very same story using the headline...
Dambuster Dog is Now Digger !
Yes the original name of the black labrador dog as many of us know was N*gger. It is very true that this name is offensive to many people these days so you can see the film makers dilemna. However any information on the dog in the film will be inaccurate if the name is changed. A whole new generation of film goers will leave the cinema with inaccurate information. There will be heated discussion in pubs in the years to come, one group swearing the dig was called Digger with the other group, possibly the older ones, swearing it was the other one.
The original film, which is about the famous Barnes Wallace bouncing bomb raid on the dams in Germany..was the staple diet of film goers in those far off days when British cinema was a socially accurate document of the times we lived in. Richard Todd played Guy Gibson and Michael Redgrave the batty but brilliant professor.
