Changing our thriller idea

For our thriller we were going to do it set in the 1960's in the USA, based on the JFK assassination. It would have been filmed in a war bunker during the Cuban missile crisis. We decided to change the concept of our idea to the present day as it would not be as difficult to get modern day props, hairstyles and clothing. We are still going to be filming in a war bunker but the set will be more modern. In our thriller the president will still be assassinated. It will also be set in the USA. But it will expand the list of problems that could be faced in the storyline for the president. This could include present day problems that the USA face which could include crises in the Middle East and perhaps in Russia.
