He told the publication: "I should be getting a script any day, which as a fan, I'm very excited about.

The comedy series does touch on some serious issues, such as race, class and mental health, but it's balancing act between addressing real issues and finding comedic ways of telling stories around them have made the series a big hit.

The Washington Post's Dylan Matthews heaped praise on the new series, saying it was "the best TV show about prison ever made."

Mashable's Nora Grenfell also described that Orange is the New Black was what "Netflix was made for."

Harney as Sam Healy (prison manager), Michelle Hurst as Miss Claudette (Chapman's former roommate), Kate Mulgrew as Galina 'Red' Reznikov (prison-mate), and Jason Biggs as Larry Bloom (Chapman's fiancé).

It has already been rumored that Taryn Manning, who stars as Tiffany "Pennsatucky" Doggett in Season 1, will also be returning for season 2, and most of the main characters would be returning, with the possibility of some new additions.
