Okay, Modern Standard is difficult to find movie-wise.
Mostly MSA is used only in historical movies and series, and most of these are dealing with religious figures and events. Also most of them are old; from the 90s, and if you are not into middle ages history then they will be boring. Some are relatively new ~10 years old but they are still into the historical genre.
Alternatively, you can watch some cartoon, manga, and anime dubbed in MSA - if you are into children cartoons - at least they will be new and relatively less boring.
