There are plenty of areas to spend $$. You can go through a ton of cash just by buying movies that are opening in the next 6 months, year, 2 years, etc... Be sure you own all of the big openers for this time. Check out which bigger stars are coming out in movies, and be sure you own those movies as well.
Usually at the beginning of each year, I review what movies are coming out that year, and make sure I own them all... this takes some time, but it allows you to buy them and sort of "forget them" as they climb over time... it may not make you as much $$ as some shorter term gains, but it's easy money.
While I don't own every movie stock, I still find there are many movies that I find and buy as time goes on, so with your port it should not be that hard to find movies to invest in. If you're looking for faster, shorter term money, then you may want to be sure you own (long OR short) movies that are opening soon.
It shouldn't be that hard to burn through $200M if you own movies that are further out.
