When several taxi drivers aim guns at Benoît, Spaghetti-western style (c. 1:03), one of the drivers is clearly aiming with two of his fingers. The guy next to him has two guns; and another driver who has no guns, chooses to not aim absurdly with his fingers but instead just look at Benoît, doing nothing with his hands.
When Dussiflard goes to Poilonez's office, Benoît waits outside, and Poilonez stays at his desk during the whole scene, so Benoît does not see Poilonez (In the comic, Poilonez greets Dussiflard at the office's door, so Benoît sees Poilonez). Soon afterward, Benoît approaches Poilonez outside the building and recognizes Poilonez as the company manager - but Benoît had never seen Poilonez before, so he should not recognize him.
