Ratings for films in cinemas - how they vary across the globe

Throughout the world, different countries censor films with different age ratings, from using the IMDB website again I can see what films that would be considered to cause little offence would cause greater offence in other countries. This is mainly based on the DVD releases, some can be the actual cinema ratings.

Here are a list of Films and the rating in the UK, then any countries with a surprising change in rating:

Titanic’s UK rating was 12 in South Korea it was considered an 18, even more closer cultural countries to the UK like Norway had its rating at 15:
http://www.imdb.com/title/tt0120338/

Also with Batman begins with an age rating of 12A verging on PG, but again Norway opted to censor it at 15:
http://www.imdb.com/title/tt0372784/

But there are cases where the UK seem to over rate films or so it would appear, Christian Bale starred in American Psycho in 2000 and the UK censorship board gave it a rating of 18, where as Denmark and Japan opted for a 15 rating:

You could argue that in particular countries try to limit the number of people who try to watch a film as it may have a negative or derogatory reflection of a particular country, its also a case of politics, some countries try to keep its population in its own ideologies and representations such as communist countries like South Korea, China and particular former Soviet states.

How much info can we get about up coming films and sequels?

Looking on good old IMDB I wanted to see how much information I cud get on upcoming sequels and whether certain aspects of information is true or simply blogged info put in by someone who has no idea, or is merely putting it on there for fun.

I wanted to find out any information about the sequel to Batman Begins, so I typed Batman into the search engine on IMBD and it gave me a fantastic list bibliography of possible matches:
http://www.imdb.com/find?s=all&q=batman

The film isn’t dated to come out in cinemas for another year but I wanted to see what info I could view, firstly I was intrigued to discover the cast list has been included and that actor Christian Bale is in the sequel which is a good for fans, also its interesting to see what characters are going to be in it, the return of The Joker will be much appreciated by fans.

On the Batman Begins 2 IMDB page: http://www.imdb.com/title/tt0468569/ as its working title is referred to it also happens to list the alternative project names its been given such as:

Rory's First Kiss (USA) (fake working title)
Untitled Batman Begins Sequel (USA) (working title)

A feature I like that allows you to save you time looking for information is the FAQ section that attempts to answer some of the burning questions related to the film in question, this feature is very good and is only updated by people in the industry so no lies.
