Speaking to Showcase Cinemas, David Heyman played down speculation that the sixth instalment in the magical franchise would be aimed at a more mature audience.
"I don't think that it's any darker than the fifth [Harry Potter And The Order Of The Phoenix]. I think it's on a par with that," he said.
"Everybody obsesses with the darkness but I think that ultimately it is very accessible, very moving and exciting."
He went on to say that Half-Blood Prince was a "real step forward", explaining: "With each film we try and push the boundaries a little bit. It's a very different film and we're exploring many different characters from Slughorn, to Malfoy, to Harry.
"There's lots of romance, some adventure and great relationships."
Harry Potter And The Half-Blood Prince is released in the US on July 15 and the UK on July 17.
