Can I still make it into film production without a gcse/a level in drama? Watch
I'm currently applying for post production and digital film courses at uni and I'm only going to get 2 A Levels at the end of this year - art and geography. Every university I've looked at so far that offer these courses have said they don't mind what subjects I take, as long as I achieve two A Levels so I would say that in most cases it won't matter if you don't take drama. There may be some courses that require specific A Levels so maybe look around a bit but I would say for the majority no you won't need drama. If you definitely don't want to study drama and the performing aspect of it at uni but you do want to study the production side then something similar media studies may be more useful.
Basically, you should be okay! I'm applying for editing and post production at Ravensbourne and they just need 2 A Levels regardless of subject choices!
Hope this helps
Your father is absolutely right, a degree in a "proper" subject is a very good idea. It will not restrict you in any way (you certainly don't need any drama qualification at all) and is generally more highly regarded by employers than a media degree.
You should know that video games designing and film making are two very different and distinct careers with very little in common though!
