The King's Speech director has discussed the difficulty of editing down the musical, and the possibility of releasing an extended version of the film.
He told Collider that he had to "become more expert at the detail of musical construction" in order to edit and reduce the length of sections featuring musical numbers.
"I used to think definitely I would do a longer version, [but] having been through the oil tanker that this thing is, to wrestle it to where we got it, I'm aware that the moment you go, 'Let's go back in', it's not a simple process," said Hooper.
"But let's see how it goes, and if we feel there's tremendous demand I'd always consider it. It's difficult, because at the same time I feel that I've paced it as I wanted it to be paced, and do I want to put out in a world a less well-paced version?
"I'm not sure. If there's interest in the community of fans of the musical then I would definitely consider it.
"I'd probably put maybe 15, 20 minutes back. I wouldn't go back to the four-hour spectacular."
Les Misérables entered the US box office chart at number three last week, behind newcomer Django Unchained and The Hobbit: An Unexpected Journey which maintained its number one spot for a third week.
The film is released in the UK on January 11.
