Referencing/displaying other films in mine...

[Sulaco]

I've got a quick question which I'm unsure about and thought some of the more experienced members here would be able to help me with.

I'm writing a short film at the moment to be shot later this year, likely August/September, and in it one of the main characters is "inspired" in to her career of choice by a certain actress and several of her films, and I was wondering what the legality is in regards to showing off the films/actress in my film?

They would be displayed on TV sets and referenced by name.

My understanding is that it's ok to use the name (as long as it's not slandering the actress etc) but I'm unsure about using the film footage. Any help would be greatly appreciated!
