Weeks after the final instalment, The Hunger Games: Mockingjay - Part 2, opened in cinemas worldwide, Lionsgate executive Michael Burns has admitted he would love to keep the franchise alive by exploring the back story of Jennifer Lawrence's character, Katniss Everdeen, and others to include the child fighting stadiums featured in Suzanne Collins books, which the movies are based on.

Burns made the admission this week (begs07Dec15) during the UBS Global Media and Communications Conference in New York, where he compared The Hunger Games series to Harry Potter, claiming it will "live on and on and on".

"The one thing that kids say they missed (from the early Hunger Games films) was there was no arenas," he said. "If we went backwards there obviously would be arenas."

Burns also admitted he was disappointed the fourth The Hunger Games release had failed to match the outstanding box office debuts of its previous three instalments, but confessed it was a "high-class problem" to have, according to The Hollywood Reporter.

Mockingjay - Part 2 opened with an impressive $101 million (£67.3 million) take during America's Thanksgiving holiday weekend (27-29Nov15), down from the $121.9 million (£81.3 million) last year's (14) Part 1 earned during its first weekend on release in the North American market. However, it has still performed well globally, grossing over $524 million (£349.3 million) to date.

During the UBS Global Media and Communications Conference, Burns also claimed he and his fellow Lionsgate chiefs are keen to do more with its other big franchises, including Twilight, The Expendables and Saw, although he did not elaborate.
