Rain is also very difficult to film, particularly in Ireland because it's quite fine, so fine that the Irish don't even acknowledge that it exists.
Personally I am very much against the death penalty for several reasons.
Period recreation is very difficult unless you make a black-and-white movie.
Most directors have little lists in their heads of people they really want to work with.
A great movie evolves when everybody has the same vision in their heads.
The films that I do tend to polarise people's views.
