My advice would be not to do something like a named degree in Film, Writing or whatever. Go for a more traditional subject like English.
Employers are extremely suspicious of degrees that look like they've trained you for a specific job - and are quite often not 'academic' enough to be useful in any other career - or sound 'silly' (Film Studies or Creative Writing for instance).
Your chances of making a career out of any form of writing is slim, the chances are that you will end up in something totally different, now or later in life. With a niche 'named' degree you'll end up explaining it for the rest of your life. If you do a more straightforward subject (even as a combined subject degree - English with American Studies etc) its actually MUCH more useful, because you havnt already closed a whole variety of doors by doing a seemingly vocational degree or given yourself a way out if you change your mind about a future job during your degree.
If you look at the structure of many English degrees, they usually incorporate some writing units or stuff like cultural studies, and other forms of writing like TV/Film etc. This gives you a degree in 'English' but without the implication of the other 'silly sounding' subject.
