I applied for film production at university this year so I understand what you've been doing. I don't know heaps about loads of different universities but the ones I applied to are three of the top courses in the UK for film production so I would recommend looking them up and obviously reading other threads about where other people have applied to. Also, UNISTATS website is really helpful to see employability rates, how much of the course is practical/theoretical since you may like one more than the other. Some websites also do a virtual tour, especially arts universities as they filmmakers so there are usually at least some way for you to get a glimpse of what university life is like there.
So I applied to:
The university of Westminster (Film) - out of all the ones I applied to, from what I understand this one is the least practical but is still obviously very practical. You work in large groups to make films and have to specialise in a certain area after year one. The media school is based on the Harrow Campus which I think is in London. I didn't realise this when I applied but the accommodation is super expensive. I think the average cost of a room is probably just under £200 a week which is so steep but of course this is because all of the accommodation is in London. London has the advantage of being in the centre of a media hub, there would be more work experience opportunities here rather than a city more out in the sticks but in terms of getting a part time job that could cover the expensive accommodation...good luck. When I visited Westminster (I didn't go to an open day, I just saw the campus at my interview) it seemed quite chilled, relaxed, there was definitely a nice vibe and the facilities there are great so I would consider them!
Arts University Bournemouth (Film Production) - this one is probably the most well known film course possibly in England. It is very competitive and promotes itself as very exclusive. Doing film here at such a recognisable university would most likely be a very good thing. The campus is all in one place unlike Westminster and Norwich where the campuses are spread out in separate buildings, and the university is right next to Bournemouth University so there would be a lot of students, not just arts students around you. When I went to the open day and interview here it gave an amazing vibe. There is work up on the walls and professional and student exhibitions in the university which makes it feel super arty. Out of all the universities I visited, this one definitely have the best atmosphere. One thing they encourage is interaction between students on all the different courses, like working with the costume designers and the actors and making films in your spare time, writing scripts for others in different years...The whole feel of the place was great. Here you have to specialise which is for me their only let down for me since I don't want to specialise...The accommodation at AUB isn't ridiculously priced and there are lots of shops around so it shouldn't be too hard for you to find a job either.
Norwich University of the Arts (Film and moving image BA) - I love this university. Norwich as a place is very safe, its near Norfolk which is super green with loads of good landscapes. Norwich has lots of little independent shops that I'm sure you could find a job in, it has a big shopping centre nearby as well. The atmosphere when I went was really friendly and quite...maybe "urban". Once again, like AUB its a largely practical course and they encourage you to interact with other courses like animation to make films which is great. Here you don't have to specialise, which I think is a real selling point and they are the top specialist arts and design university in the country. Unfortunately from what I understand there isn't enough accommodation for all first years students so some will have to either live at home and commute or find a house instead of live in halls. But since you live overseas you should pretty much be guaranteed accommodation so you shouldn't worry about that too much.
Obviously I applied for primarily practical film courses so if you want more theoretical you'll have to look into that...I hope this helped a bit and you could private message me with any other questions you have if I can help!
