The uncut version of "The Woman in Black" was rated 15 by the BBFC. The distributor chose to have the film cut in order to obtain a family-friendly 12 rating for cinemas. Understandable, I guess, because cinemas are an age-restricted environment and a lot of Harry Potter fans would've been refused entry if it had been a 15.
Sadly, though, it looks like they've chosen to put that same cut version out on DVD/Blu-ray in the UK.
Let's be clear: this is not a case of repugnant or unacceptable material being cut, it is a case of a film being deliberately and optionally toned-down purely to lower the rating by one notch so the distributor could increase their sales.
If you buy the 12-rated UK DVD or Blu-ray then you are voting with your wallet and sending a message to distributors that it's OK by you if your films are cut for commercial reasons.
Is that OK by you?
