No such Russian name

This mistake is made in a lot of movies with Russian characters in it, over and over again. Often, if not always, the last names or even the first are completely unrealistic since they are simply incorrect and do not exist in Russian culture. I am Russian by birth, and I would know.

For instance, "Chenkov" is a male name. All Russian female last names that has a "v" towards the end have an "a", so the correct character's name would be "Chenkova".

I know, you would ask me, "So, who cares?" I do. And Russian viewers do. I can only imagine the reaction of russian audiences in Moscow movie theaters. "That's wrong", there would be shouts.

And mistakes like that are abundunt. And not just about names. And I am really tired of that, and irritated. And willing to work as a consultant on movies concerning Russian characters. :)
