When I went to N&A in the movies, I found the introduction of that inaccurate "Yurovsky" brought comic relief to the audience. Most everyone either chuckled or laughed out loud.
That was I didn't like it. The audience which consisted of many who knew nothing of the real participants thought that Yurovsky was funny!
I didn't see any benefit to making the man look older and and almost senile even though he was, of course, not senile at all but the brutal executioner of the whole family.
It made no sense to someone who knew the story and provided a false impression to those who didn't. I am not saying that movies should teach, but the producers went very far in trying to make the major characters, Nicholas, Alix, Rasputin, Nicholas Nikolaevich and even Dowager Empress Marie look the part, the complete reversal of Yurovsky to look like someone he wasn't made no sense.
