The young actors who play Harry Potter and his two best mates might outgrow their roles, a producer of the hit movie series has warned.
David Heyman told the New York Post:
"There will come a point when one, two, or all three of them will move on."
Dan Radcliffe, Emma Watson and Rupert Grint have played Harry, Hermione and Ron in all three Potter movies.
But the time it takes to get the movie out means they might be too old to play the roles by film five, six or seven.
