What are the famous slit shots in film history?

Hugo is highly recommended. The opening shot overlooks the panoramic view of Paris in the early 1930s 1968+0930. Then the shot falls, gets into the station, marches side by side with the train, passes through the crowd, and finally comes to the big clock, aiming at the protagonist hiding behind. It took a year for this lens to be shot for the first time. The rendering used 1000 computers, and the duration was 50 seconds, which was just the length of "Train Entering the Station".
