When Alain is crossing the road, a man pushes him over to save him, throwing his books on the floor. The next scene, both men are seen picking up the books. The cut between both scenes is visibly clear.
As Alain walks on the streets of Paris, the crew (pushing the dolly) is visible on the shop windows he passes by.
When Alain opens the door to exit the taxi near the start of the film, the camera is reflected in the window.
