"The Royal"

Another 4th year idea (and comic premise) I've been working on is "The Royal". A gang of almost vigilante-like criminals set in post war 1940s. The animation premise would be the 3-4 character I have so far to rob a bank, but getting betrayed by one of the members. After a shoot-out, they're arrested by their betrayer, only for this to have been the intention all along - the gang then racing off with the money in a stolen police car. Again, this is an idea I keep coming back to and working on in the background, but haven't tied too much down yet story-wise for the comic idea (which would be a serial or one-shot). More research needs to be done into the time period and using that to help assign the roles of the gorup, the vehicles, gun models etc. and help it be authentic in detail.
