There are some new and more prominent faces in Harry Potter and the Half-Blood Prince, and I thought this list would be a nice precursor to the film for all you Pott-heads:
22-year-old Jessie Cave will play Lavender Brown, Ron's new love interest, and Hermione's competition.
22-year-old Freddie Stroma will play Cormac McLaggen, an obnoxious member of the Slug Club, Professor Slughorn's elite club, who competes against Ron for the position of Keeper and later takes Hermione to the Christmas party, so she can make Ron jealous.
17-year-old Anna Shaffer will play Romilda Vane, the girl who crushes on Harry so hard she spikes chocolates with a love potion to seduce him, but ends up seducing Ron instead, which ultimately leads to his near-death experience.
Alfie Enoch will reprise his role as Dean Thomas and become a thorn in Harry's side as Ginny starts to date him.
18-year-old Scarlett Byrne will play Pansy Parkinson, Malfoy's devoted love interest.
19-year-old Georgina Leonidas will play Katie Bell, who is almost killed by Malfoy as he performs the Dark Lord's orders.
10-year-old Hero Fiennes-Tiffin, Ralph Fiennes' (Lord Voldemort) nephew, will play young Tom Riddle...very convincingly. lol
