hello
I have a question. What is the difference between the pcb layout and films?

PCB layout is used to enable someone to make a circuit board.

Films are entertainment that we watch on our TV

So can you explain more about your question, what films? what form of pcb layout?

You can layout a PCB directly onto film for the photo-etching process and you can layout a PCB using an ECAD package, the output from this Gerber data generally is then processed and put onto a film using a laser printer, these films then being used for the photo-etching process.
An example of PCB film:
