Add Additional Actors Using NFOs

Is it possible to add more actors to what is scrapped from TheMovieDB? I used the following:

Code:
<?xml version="1.0" encoding="UTF-8" ?>
<Movie>
    <actor>
        <name>Gipper</name>
        <role>TestActor</role>
        <order>0</order>
        <thumb>smb://KODI-PC/K/Movies/Gipper.jpg</thumb>
    </actor>
</Movie>
https://www.themoviedb.org/movie/389

…and I only ended up with Gipper. I really would like to do this using NFO’s and not manual entry.

Any help appreciated.
