shouldn't "фильм" change into some type of possessive form? or does it not have a possessive form? or am i confused about what possessive is? SOS
The noun that's possessed doesn't take the possessive form (or "Genitive" as it's usually called).
It's the noun that possesses something else that does. Imagine the genitive like adding "Of the-" to the start of a noun. "Человек фильма" - "The person of the movie". "Фильм человека" - "The movie of the person".
Couldn't this be "this is my film" as well as "it is my film"? How do you differentiate?
I suppose both the sentences are correct and either one can be used in place of other
What is the gender of фильм and of мой? I suppose masculin but I am not sure..
