Life on mars is a britsh science fiction/police drama televison series it is broadcasted by the BBC.
The cinematic techniques (camera and mise-en-scene) in this episode are used to show the differences between to era's. The camera does this by showing the audience an establishing shot of a modern day car then later on in the scene we see a shot of an old fashioned run down car. The mise-en-scene does this by using the costume, it shows the officer in a suit which is a convention of police clothing then later in the other era we see him in more casual clothing this shows us that the dress code for police has changed over time.
