If you have IOS9 ou IOS10 you can still install MovieBox without having to jailbreak your device.
For that you will have to install tweakbox on your device.
Go to tweakboxapp.com (on your IOS device), select "Get the APP" and press install to install the certificate and the app itself.
Open TweakBox, select Apps..
Then TweakBox Apps.
Select Movie Box, then press install.
If you have an Android device you can use ShowBox, which is the same.
