Quote from : Harry Potter and the Goblet of Fire Movie

[the Trio sits around the fireplace in the Gryffindor Common Room, digesting the murder of Barty Crouch, Sr. that has just taken place]
Ron: They'll cover this up, you watch. Fudge'll sell his soul before this gets out in the Daily Prophet.
Harry: But why?
Ron: Look, nobody liked Crouch. I know this from my father. Loads of people wanted him dead. But, he was a Ministry Official. It's not even like he turned up stiff in Knockturn Alley. He was murdered at Hogwarts. This is a big deal.
Hermione: It can't be coincidence... Harry's dreams, his scar hurting, the Dark Mark, his name coming out of the Goblet of Fire. Surviving the Tournament isn't the answer anymore Harry. It's bigger than this. And I really think you should go to Dumbledore.
Ron: Yeah.
