'Pretty Little Liars' series finale will be a 2-hour movie, creator says

"Pretty Little Liars" creator I. Marlene King revealed on Wednesday that the final episode of Freeform's massively successful drama will be a two-hour movie.

The final episode of the series is being co-written by King and Maya Goldsmith, with King set to direct. "We are treating that as a two-hour special event movie," she said.

In a conference call with reporters following Tuesday night's midseason finale, King discussed the deadly episode and the upcoming final 10 episodes, calling them "the most powerful 10 [episodes] that we've ever had."

On Monday, King was joined by series stars Lucy Hale, Ashley Benson, Troian Bellisario, Shay Mitchell and Sasha Pieterse in a Facebook live chat to officially announce that Season 7 will be the show's last.

"We are a family, and it will be hard to say goodbye to a show that has made such an impact on young audiences and been a mouthpiece for cultural change," King said in the announcement. "I'm excited for fans to finally have all of their questions answered, and I believe they will be satisfied with the wild ride that is our last ten episodes."

As for whether or not fans can expect a reboot or reunion in the future, King said she'd be open to the idea.

"We're very open to keep these characters alive, and I hope that down the line we find a way to bring all the girls back together again," King said.
