Production Concept: Changes to My Last Script

For my last script I said I was going to place my script on Dublin, Ireland, but I have never been to Dublin, therefore I don't have any idea of the surroundings. With the Paris and Rome scripts, I have been there within the last 2 years and can remember certain streets and the layout and general feel of the place. I started to write the Dublin script and struggled to imagine the place, which would have hindered me as I wrote it and make me lose interest. The item I used for the London Script is a London Underground Sign replica.
