Kinda long but hopefully it will give you an idea about what I would try out and test
Google Adsense. Create and get approved. You need a news website. It will have either fake or real news about your famous actors. You choose if it's fake news or real news because that will be your strategy on how you get traffic to your news site. You create 3 simple sites dedacted to the actors and you could think up the rest yourself. You create a news story or article, include pictures and share that story on the facebook page in hopes many will go through the link to your site and click an ad from Google. Fake crazy news might get you more traffic to site but you also could lose fans.
You have the niche audience. Try the news sites method with adsense on them and be sure the websites are very mobile friendly.
Don't forget about growing your page. Post on your facebook fam page about a contest. You will give something away to the winner. To enter the contest you will have to like the post and invite all your friends to like the fan page. Also you can make them share the contest on their facebook profile page.
