12 rated films mean that the audience has to be over 12 to be able to watch it, or they can be accompanied by an adult. These films are a significant step up from 'PG's' as they can include a bit of blood and they are allowed mild swearing. These are the borderline of adult films, as they are the start of getting into more serious topics, but they are still very mild. 12 rated films tend to appeal a lot to a teenage audience, as they allow all teenagers to see it, however this means that an adult audience may be reluctant to go and see it. The James Bond franchise is an exception to this rule, however, as it is an accepted franchise that is loved by all ages. 'Licence to Kill' was the only Bond film rated higher than a 12, but nowadays would probably be considered a 12.
I think we could consider making a film that would appeal to this classification, but maybe it's a tiny bit too mild for our liking as it cuts down on how much we can show the audience
