Is it okay not to put "the" before "film"?
Yes, it is okay not to put the article "the" before "film". This is because they are showing us several films and he is referring to them generally. If you wanted to refer to one of the films specifically, then you could place the article "the" in front of "film". "Film" here is also used as an uncountable noun. "Film" can be both countable or uncountable, depending on the context which it is used in. In this case, it is uncountable so you don't need an article before it because "film" is in the plural form.
