In a text, it is difficult to mention things subtly, whereas in a movie, you can show things without giving away their meaning.
For example, if there is an axe hanging on the wall in the movie, someone may or may not be beaten to death with it later. In the book, on the other hand, the reader would expect something to happen to it if it were explicitly mentioned. And if it wasn't mentioned, one would think: Where did this axe suddenly come from? It would appear unbelievable and weird...
In the same way, a description is usually accompanied by a valuation - especially in the first-person perspective: She's very pretty.
You know right away that he thinks she's pretty. Whereas in the film you see that she is pretty, but you don't know yet whether he really likes her or not.
(But this can also be a disadvantage of the film. In one of my written stories, the protagonist always describes a woman as particularly beautiful and elegant. Later you notice that other characters don't share his opinionat all, which implies that he got a crush on her. To show this in a film, however, would be difficult, I think).
