Would Criminology and Film and TV studies be a good degree? Watch
Although it could be that having a degree as well as this experience sets you apart but the experience really is the key part. Go to a uni that is really strong in this area - it may be completely unknown to everyone else but if it is respected in the film industry, that will always give a bit of a leg-up.
The other thing would be what are you wanting to be in the future - a criminologist or in tv production. Could you do one as a minor so as to get the most opportunities in the other area?
If you love these areas of study then absolutely go for it as enthusiasm can go a very long way.
