Okay so I know a lot of films make references to other films, and it may sound like a bit of a daft question, but it is something I have thought about and must ask. 
Are there any legal issues around referencing? I enjoy making references when i talk to people in everyday life and would love to put most of the references into films for the comedy factor
Any help would be most appreciated
