Pattinson first cast a spell on fans as Cedric Diggory in &quot;Harry Potter and the Goblet of Fire.&quot; The story unfolds around the Tri-Wizarding Cup, a competition among the three magical academies. Cedric is chosen to represent Hogwarts, but somehow Harry's (Daniel Radcliffe) name is chosen as well. We won't tell you who triumphed at the tournament, but we can say that the movie was a blockbuster success, earning more than $290 million at the domestic box office.
