3. Clémence Poésy - Fleur Delacour
Clémence Poésy was featured heavily in the fourth film and made sporadic appearances throughout the rest, where she played the gorgeous Frenchwoman Fleur Delacour. She was one of the champions of the Triwizard Tournament in Goblet of Fire, and later married into the Weasley clan after falling in love with Bill. Over the years, the young actress has been working to find a balance between projects in her native France and English language productions. Despite having a short run on American television with her recurring role on Gossip Girl, she seems to have found a home working on largely international productions. In the years following Goblet of Fire, the film in which she had a much larger role, she starred in an adaptation of War and Peace as Nastasha Rostova. Since the series has ended, she was in Birdsong, a romance set in World War I, alongside Eddie Redmayne (Les Miserables). Currently, she stars in a Canal+ television show called The Tunnel, which is a drama about a pair of detectives investigating the mysterious death of a French politician (an adaptation of the Scandinavian program called The Bridge, which has also been remade for the American market).
2. Tom Felton - Draco Malfoy
Probably the most experienced actor of all the children on the Harry Potter set during the early films, Felton had been in several films before being cast as Draco Malfoy. He is the secondary antagonist of most of the films, a preening rich boy who believes that his pureblood lineage elevates him above his classmates. Despite the fact that while the films were being made (especially early on), Tom Felton vocalized his desire to quit acting after the Harry Potter series was finished, he's had an admirable career since then. The biggest concern about Tom Felton was whether or not he would be able to escape the fact that, after playing Malfoy for so many years, most people wanted to punch him in the face. He had played likable characters before Harry Potter, but could he do it after? Well...kind of. Although his first big post-Potter role was as another minor antagonist in Rise of the Planet of the Apes, he's managed to have quite a diverse CV. He doesn't seem to be under any illusions that he's going to be cast as the romantic lead anytime soon, he's cultivated an interesting list of roles that hint at something that goes beyond what he was able to showcase as Draco Malfoy. He's got two major films in the works right now: Ghosts of the Pacific, where he plays one of three US airmen stranded on a lifeboat in the middle of the ocean, and Fangs of War, where he plays John Seward in a new interpretation of the Dracula story.
