Couple questions.

Rating and votes... I never really concerned myself with these but I've decided to start including this in my metadata. But particular metadata like this is always changing.
So if I scrape a movie today and import it into Kodi using only local information is there any way to have current up to date info for this?

Media Companion was developed so users could scrape the Movie/Series/Episode nfo's locally, had have control over the data, images etc before they are scanned into Kodi.
Unfortunately Kodi has no method to rescan existing nfo's for changed metadata, meaning once the nfo has been read and loaded in Kodi's database, Kodi will never again look at the nfo. Except if Forced to update from local data (usually one at a time) or by removing the source, don't delete, and then re-assigning the source and allowing Kodi to rescan all nfo's and update the database.
This is time consuming, and tedious.

Now, If Votes/Ratings are the only thing you wish updated in Kodi, I would suggest Texturecache.py by Milhouse. https://forum.kodi.tv/showthread.php?tid=158373
While Texturecache will not read from the nfo, it will get latest votes/ratings from the web and update Kodi Database directly.

Sory, there is no easy, one hit way to get this done.

Also was thinking about actor images. I've often wondered why there wasn't a single actor database instead of the repetitive files... Since every movie has its own actor folder if you have an actor in 30 movies you will have 30 files for that person. Since that is how it works is there any way when scraping a movie for example from the 80's... to get an actual actor image that is current to the movie? I mean if I have actor images from a 40 year old movie with a current image you might not even recognize them... especially when you get to actors over 60 or 70 years old... Obviously doing this manually would be damn near impossible especially for libraries for 1000+ movies but if there was a database set up for this....

For the first part of this how about setting up MC to store actors in a central actor folder. See Wiki - Preferences -Actors

As for getting actor images for the age they were for specific movies, There is no current way to get this done.
I think it would be great nostalgia to get Images like these for Actors, but I haven't seen or heard of any site, or method, to get those images.
Manually is the only way for now, and yes, would be a pain in the but. 

Thank you. I will look into Texturecache.

As for the actors. If I would decide to go with a central folder would a local one take precedence if I decided to do so?
Meaning I put all my actors in a local folder then decide I would like to do what I mentioned with select movies and have an actors folder in those movie folders. Would Kodi prioritize those when scraping or is it a one or the other thing?

As for the actors by year thing I think it is something that could actually be done it there was enough interest and people got involved. I mean movies in the last 5-10 years would already be fine for the most part. Then if you acquire an actor image from 1980 for example that image could be used for a few years of movies from that timeframe. I'm sure the sources are out there with Google, then and now websites comparing actors and so fourth. Or maybe its just too much effort... I'd say at the least I'll do this for some movies in the future.
