Actress Emma Watson is likely to return as Hermione in the last two Harry Potter movies despite reports she may quit, producers Warner Bros have said.
Filming of the sixth Harry Potter movie is due to begin later this year
"We're extremely confident that Emma will be back for films six and seven," a spokesperson for the Hollywood studio told CBBC's Newsround.
The statement comes amid speculation that the 16-year-old told the company she did not want to continue.
Daniel Radcliffe has already agreed to take the lead role in both productions.
There have been four films based on JK Rowling's books so far, with the fifth - Harry Potter and the Order of the Phoenix - due for release in July.
Filming for Harry Potter and the Half-Blood Prince is scheduled to begin this year, with a release date at some point in 2008.
A release date in 2010 has been mooted for the seventh and final movie, The Deathly Hallows - the year Watson will turn 20.
