If you're not willing to get a portfolio together off your own back then that's why universities will reject you, not because you didn't have Media Studies A level.*
You don't seem to have the best attitude if you want to become a film director. The people who make it to the top are the people who live and breathe celluloid. You're letting the fact that your school doesn't run a fifth rate A level stop you.
I will also point out, though, that you're actually incorrect on one point. There are a number of courses which don't require a portfolio for their courses in film and television production. Doing a facilitating subject would be more of an advantage for those schools than media would anyway. York and Warwick are two that you should look at.*
