DVD cover brainstorm

I have looked online via Google images at a variety of different DVD covers, to see the different styles. All of these are from different genres but that does not necessarily mean that these are the conventions for the different genres, I have chosen these because of how different they are in comparison to each other. It helps to see what the expectations are depending on the budget, for example the Hunger Games cover has a lot more to the detail of the cover in comparison to Friends with Benefits which had a much lower budget. Therefore this is the aim/goal to get to with my front cover.
Some of the similar conventions that I have found though are:

• The title is much larger than any other text on the cover
• all of the main actors names are located at the top of the cover.
• there are a variety of different pictures on the back to give an insight of what will be in the film. 
• There is a brief summary of the narrative so the audience know what to expect.
• The main image is of the main characters
• The credits are located at the bottom back of the cover.
• The barcode is either at the top of the back or on the side at the bottom.
