Say NO to hard work!
You want to find common cast between two movies? Or set your friend straight in that argument over whether two actors starred in a movie together or not?
So you say you can open a few tabs in your browser and search for your movies and cast, and go back and forth comparing them? But that's hard work! And although hard work never killed anyone, but why take the risk? Commonly can do the tedious work for you, and give you exactly what you want to know in an instant.
Commonly is an extremely lightweight and simple to use app to do just that! In fact, it's also the FIRST and ONLY app that does this on the App Store.
