Continuity mistake: The movie starts and people rush under a heavy rain. A group walks by the fruit stalls, and a sellers bumps into them and walks towards the camera. A frame later there's a quick cut and, though the angle remains the same, the people have vanished and been replaced by different actors, plus the seller has turned around and is walking away from the camera. Really odd. (00:04:35)
Continuity mistake: When the move starts and rain is pouring, a worker uncovers a tarp from a fruit stall, half a second later the tarp is on and he uncovers it again.
Continuity mistake: In the scene where Eliza starts to sing the song "Loverly". She goes "all i want is a room somewhere." and at ". oh wouldn't it be Loverly" she sits down and her apron is halfway between her legs. When she continues the song the angle changes and her apron is now covering both her legs, at her right a man disappears and at her left a woman, at her left a man walks later than in previous angle the sacks behind her change formation and the carriage wheel is now lighted.
Continuity mistake: When Higgins scares Eliza to force her into being her pupil she is either standing in front of a barometer or next to it. (00:43:10)
Continuity mistake: During "Loverly", a man throws lettuces up in the air. The amount on the floor changes between shots.
Continuity mistake: Eliza bumps into a man looking for a taxi and drops her basket three meters behind. When she stands up the basket is on her hand.
Answer: He knows that Professor Higgins is trying to pull a fast one by having Eliza pretend to be someone else, and he fancies himself as much of a linguistic expert as Higgins. He's correct that there's something going on; he just gets the wrong end of the stick and assumes she's "high born," thus proving Higgins right that he could "train" Eliza to pass as upper class.
