Felton appeared as Potter's enemy Draco Malfoy in the final release in the franchise.
He teased that fans will be treated further by a "mega edition" DVD of the last film, while appearing at the premiere of his latest movie Rise of the Planet of the Apes.
"They shot a bunch of stuff," he told MTV. "There are documentaries and us doing all sorts of [things on set]. You saw us playing golf last time.
"There was all sorts of crazy stuff. They were trying to compose this mega edition."
Harry Potter and the Deathly Hallows: Part 2 is expected to be released on DVD and Blu-ray in the UK in November.
Felton recently revealed that his dream ending to the series would have involved Malfoy taking over.
