Unless I'm mistaken its around £2k in fees for a 325 minute series, and it increases linearly so around 4k for 650 minutes etc.
I don't know if there are ways of minimising this, ie removing the per-minute cost of all the opening and endings after having been rated once they can be removed from the total viewing, and therefore chargeable, time.
Its a decent chunk of cost, without it I imagine we'd see a lot more of the episode heavy series' released. Take Monster for example, it would cost in excess of £10k in fees just to rate it.
Out of interest....Lets say someone licenses Monster, and all numbers here are plucked out of the air:
If the terms of the agreement charged the licencee say £1,500 per episode, and they made 2,000 copies available, sold to retailers at £100 a pop, and packaging cost £5 (it will be less than this) per unit, plus BBFC charges, plus assuming a team of 4 each paid £25,000/yr and it took up exactly 1 month of their time, it would look like this:
Licence cost: £111,000
BBFC Fees: £13,000
Employment (1 month total hours): £8,333
Packaging: £10,000
Total: £142,333
Now that doesn't include printing, shipping, negotiation, advertising, rent etc etc, but forgetting for a second those things exist, if even 500 units couldn't be shifted then you're only on £150,000 recouped, which is incredibly close.
You've got to be pretty damn sure it's not just the voice of the hardcore few online that really want to see a series brought to these shores, and put their money where their mouth is. To that end as much as I would love to see some of the large classic series released, I understand that it must be a gamble sometimes.....but then if you make £5k profit per release after all is said and done and have 20 releases in a year that's a nice £100k profit at the end of it, so fine margins are the name of the game I expect.
