The 'Big Bang Theory' boss Bill Prady doesn't like to plan episodes so has no idea how the finale will pan out.
CBS announced last month that the US sitcom would conclude for good after the 12th season, but co-creator Bill Prady has admitted he's still unsure how the final episode will go because him and the writers prefer not to "plan ahead."
Speaking to UsMagazine.com, he said: "We're approaching the final season the same way we've approached the 11 seasons before: with no planning whatsoever. From day one, we have never planned an arch for a season. We don't plan ahead, we just kind of just tell the next story."
And, although he's still got another instalment to produce, Bill already knows he's going to miss the cast - comprised of Jim Parsons, Johnny Galecki, Mayim Bialik, Melissa Raunch, Kunal Nayyar, Kaley Cuoco, and Simon Helberg - because they all get on so well and have developed a strong friendship over the years.
He explained: "I'm really, really gonna miss these people. It's a cliché to say everyone is friends and we all get along, but everyone is friends and we all get along and we all love each other. I will miss them very much."
