I got one little thing a learned form experience;
The more 'actors' (friends) you ask for playing in your video, the more views you will get (and even a little boost of subscribers )
This is how it probably works:
If you just played a role in someone's video, you will probably post it on your facebook, twitter, etc. including a link to that video. Other people also do that. So if you have 5 people doing a role in you video, they will all post it on social media and their friends and family will see it too. This way, you get a bigger audience and a higher amount of views, subs and likes (and probably some extra comments )
