There have been discussions about a sequel to Netflix's comedy-drama series Orange Is the New Black, which will end with its seventh season next year.

US entertainment industry website Deadline reports that the maker of the show for Netflix, Lionsgate TV, has been in talks with the creator of the series, Jenji Kohan.

"We're already in discussions and, when the timing is right, we'll talk further with Jenji about a potential sequel," Lionsgate Television Group Chairman Kevin Beggs told reporters.

Last month, Netflix announced on Orange Is the New Black's Twitter page that the show was to end, saying: "Warning: This may make you cry. The Final Season, 2019."

It attached a video of the cast of the show paying tribute to their fans, with star Uzo Aduba saying they "will not be disappointed" with the finale of the prison-set series.
