We found this nice review of “Linda McCartney Story” and this photo in good quality. 🙂
But Elizabeth Mitchell is just as good as Linda, she may not look exactly like Linda McCartney but she does this fantastic job of playing the character and in particular getting across the depth of feeling that Linda had for Paul. It is because both Mitchell and Bakewell commit to bringing the love story to life that you end up forgiving some less than good casting such as Canadian Matthew Harrison doing Mick Jagger. And the good thing is that most of the bad casting choices come early on so get past them and it gets better.
What this all boils down to is that “The Linda McCartney Story” is actually not a bad movie considering it is a TV Movie. It has issues such as some poor casting but with the emphasis being on the relationship between Linda and Paul it does a good job of getting across the love they hade for each other.
