Dudley Dursley is Harry Potter's cousin, the son of Vernon and Petunia Dursley. Dudley is a muggle who was raised to believe Harry was worthless and that Dudley was perfect. He was extremely spoiled and often bullied Harry with no consequences.
In the fifth movie, Harry saves Dudley's life and Dudley later begins to gain some respect towards his cousin.
Dudley Dursley is played by Harry Melling in the movies.
No, Richard Harris played Dumbledore for Sorcerer's and Chamber. Michael Gambon acted as Dumbledore for the rest of the movies.
Yes, in each movie that Vernon Dursley appeared in he was played by Richard Griffiths.
No. Richard Harris played the role in the first two Harry Potter movies. He later died and the role was given to Michael Gambon.
The actor is the same, yeah.
Yes
Voice actor? Mitsuaki Madono. Same voice as Kon in Bleach.
No. I actually believe WizTech is an imitation of Hogwarts.
Yes. Lou Antonio is both an actor and director.
The "principal actor" is the same as "lead actor". This would be an actor who has a major role in the movie versus a supporting actor or an extra. An example would be Johnny Depp as Captan Jack Sparrow in Pirates of the Caribbean versus Geoffrey Rush as Captain Barbossa.
Gellert Grindelwald was Dumbledore's childhood best friend, so it can be safe to assume that they are around the same age. There is no age given in the books for either of them, but Dumbledore is often described as extremely old. There may be an exact age written on a JK Rowling website or of the like.
In J.K. Rowling's biography, author Connie Ann Kirk speculates that Dumbledore was inspired by J.K.Rowling's old headmaster who was called Alfred Dunn - whose initials are the same as Albus Dumbledore's. J.K. Rowling herself has never said who inspired the character of Dumbledore, it was likely a combination of people and personalities.
Not known. (The same is true for the most of the Hogwarts teachers.)
Michael Gambon plays Albus Dumbledore in all of the Harry Potter movies except for the first two (Dumbledore was played by Richard Harris in those.) and he also played King George V in The King's Speech.
No, Dumbledore has been played by Richard Harris (Harry Potter and the Philosopher's Stone and Harry Potter and the Chamber of Secrets) and Michael Gambon (the remaining six films). Gandalf was played by Sir Ian McKellen.
they are the same people
If you look at their pics side by side, you can tell they are definitely different people. However, the costume and makeup teams made an effort to make them look very similar. They were both playing the same character, and the switch could have been very distracting if they hadn't.
yes they are the same actor
It changes... it is never the same
Voice actor? Mitsuaki Madono. Same voice as Kon in Bleach.
For the same reason you can't say the name of that Scottish play, I guess!
No. I actually believe WizTech is an imitation of Hogwarts.
Not really... but there is slytherin... Maybe not, but here's same rather dark people: Lucius Malfoy (gave the horcrux-diary to Ginny) Dolores Umbridge (used a blood-quill on children) Bellatrix Lestrange Severus Snape (the worst evil bully ever) Albus Dumbledore (the Puppetmaster) Gellert Grindelwald (the previous Dark Lord)
