Seems "Harry Potter and the Chamber of Secrets" will be the only appearance of Dobby the house-elf on screen despite his involvement in three other book versions of Harry Potter series. Toby Jones, who voiced the character, has revealed to MTV that the elf, for the second time, won't be featured in the film franchise, in this case the upcoming "Harry Potter and the Order of the Phoenix."
"I know that the filmmakers have a problem with each new film because the books are getting longer - there's so much to include in them," so he said understandingly.
Contrasting with Dobby's absence in the highly anticipated movie, the other house-elf, Kreacher, who serves as the servant of Sirius Black's estranged family, is confirmed to make his first film appearance in this fifth installment of the series.
In the book version, Dobby actually plays quite important role as he is the one who shows Harry the Room of Requirement and later warns him that the secret hideout is no longer safe from Dolores Umbridge, the new Defense Against the Dark Arts teacher.
