What problem are you trying to solve?
I like that you already have a category for movies, but if you enter in a movie that has already been released, but has not come out on DVD / digital / whatever, it is not quite as useful.
Explain your ideal solution
Perhaps have a separate section for DVD / digital / whatever so that you can keep track of them separate from actual movie releases
How are you currently solving this problem today?
I have a private calendar setup on my calendar app where I enter in when movies are being released.
