The laws then forced the scenes where there was a kiss to be broken up into very short segments because in the 1960's kisses could not be longer than 3 seconds in length. Along with this, Hitchcock films featured certain details that would be considered inappropriate for that time period. For example, Alicia would be considered very inappropriate during that time period, girls were expected to be very refined and proper, but she was not like girls of this period. She frequently got drunk and put herself out there in many ways with men. 

Throughout the whole movie T.R. Devlin, from falling in love, is trying to crack down on the Nazis hiding uranium. The feud between Nazi Germany and the United States was a very big historical event and in this movie it is portrayed very well. During World War Two the United States was always trying to bring down Nazi Germany. In Notorious the U.S. Government is after the Nazis and they use Alicia Huberman as a spy. 

T.R. Devlin was just the one part of the movie while in the end him saving the girl from getting poisened and almost killed. The movie just shows how different of a director Hitchcock was from other directors back then. Hitchcock uses historical context many times in the film one of them is the when they kiss they only do it for three seconds, another is when T.R. Devlin was saving her at the end while whispering to the butler about trying to kill her.
