Eastern promises opening scene

The opening shot of the film shows the sign of a barbers shop.The shop has the barber's name on the sign in bold, blood red writing. The red writing could have been used by the filmmakers to symbolise how dangerous the barber is. This could also be linked to Sweeney Todd as he is seen as a dangerous barber by the general public in Great Britain. I think that the filmmakers have also used pathetic fallacy in this film by introducing the stormy weather at the start of the scene. This opening scene would have a much different effect on the spectator if the filmmakers had set it on a nice, sunny day, the bad weather acts as a further warning along with the sign on the front of the barbers shop. The two men inside the shop are comfortably conversing with one another showing that well acquainted. As the third man enters the shop he quickly changes the open sign to closed and closes the blinds as if he is trying to hide from something as opposed to hiding what is about to happen. As the third man walks further into the barber's shop he looks very nervous and it appears to the spectator that he is hiding something behind his newspaper. The barber and his customer continue to chat and don't seem to notice the third man's discomfort. The barber's demeaner changes as the third man walks further into the shop. The customer attempts to shake his hand unaware of the third man's obvious discomfort. The barber attempts to hand his cuttthroat razor to the third man but he refuses to take it. The barber moans to his customer about how the third man isn't willing to help him. The barber again insits that the third man should take the razor, the third man pleads to the barber in turkish saying "Azim, please." The change in language by the barber and the third man from english to turkish shows the spectator that they are both hiding something from  the spectator. The customer laughs and tells him to leave the third man alone, he then continues to read his newspaper. This shows the spectator how comfortable the customer is within this environment. The barber then loses his temper with the third man and swears at the third man telling him to finish the job. The third man finally takes the razor from the barber. At this point it is clear to the customer what is about to happen. Before the customer has the time to stand up the third man brutually slits his throat. This method of murder once again links to the idea of Sweeney Todd and it shows that is is possible that the filmmakers were inspired by his story.
