Norton appeared alongside Brad Pitt and Helena Bonham Carter in the film, which was released in 1999 and based on the Chuck Palahniuk novel of the same name. The actor told Digital Spy that he thinks changes in the home movie market have brought about a shift in filmmaking culture.
"I think it would be much harder [to get a film like Fight Club made] today," Norton told Digital Spy. "It's right in that middle budget range that no-one wants to touch anymore. And DVDs are disappearing, no-one's going to buy a DVD in three years. It was kind of the secondary revenue that prompted them to make films like that.
"The digital, on-demand and the subscription services, Netflix or Amazon, the revenues coming back from that are kind of pennies on the dollar to what it was to sell a DVD, so it's much harder."
Norton also addressed rumours of a Fight Club musical, quipping: "I will be in the second row for the premiere. I'm sure neither Brad Pitt nor I will get invited to sing in it, but that would really make me laugh."
The Bourne Legacy is released on August 10 in the US and on August 13 in the UK.
