What are Orson Welles signature traits in his films?
He is well-known for his very long tracking shots. An example is in Citizen Kane, where the camera tracks down from a cityscape, through a cracked skylight, and into a nightclub, where a woman is being interviewed. The most extreme case of this was the opening sequence in Touch of Evil, where we see the couple about to be murdered on their way across the Mexican border. This is shot all in one sequence until the car blows up. It is not one of my favorites of Welles, but does illustrate his long camera tracking. I hope this is helpful for you.
