I have seen the real Erin Brockovich and she I thought looks a lot like the grown up Erin Murphy. Gee now I wonder is the name of the Julia Robert character Erin.? Anyway the women look much the same. Gee Erin Murphy could have had the part. Maybe her acting isn't as good as Julia's. I couldn't see any resemblance in the Julia look. I didn't see the movie. Was her hair dyed?
