What does Ron Weasley say the first time he sees Hogwarts in film Harry Potter and Philosophers Stone?
In the film adaptation of Harry Potter and the Sorcerer's Stone, Ron Weasley doesn't actually say anything the first time he sees Hogwarts. He's too busy staring in awe, just like Harry, as the castle emerges from the mist.
However, he does say "Blimey." This happens just after they've entered the grounds and he's looking at the castle from a distance.
