The ABC Network has just announced the renewal of the fairly tale drama "Once Upon A Time" for a fourth season, which will premiere in September 2014.

The first season of "Once Upon A Time" premiered on Oct. 23, 2011, the second season began on Sept. 30, 2012 and Season 3 of the show was released on Sept. 29, 2013. All along the series has been aired at 8.00 p.m. ET every Sunday. Keeping these in mind, it can be predicted with fair certainty that Season 4 will have an 8.00 p.m. ET air time on Sundays starting with its premiere air date of Sept. 28, 2014.

Meanwhile, in an interview with TV Guide, Edward Kitsis and Adam Horowitz, executive producers of the show, provided some information regarding what viewers can expect in "Once Upon A Time" Season 4.

While we are already aware that Elsa from "Frozen" will be introduced in Season 4 somewhat as a villain princess, the producers said the interpretation of the character will be slightly different.

Horowitz told the website, "As for her being a villain, the thing we loved so much about that movie, among a million other things, was that Elsa was misunderstood."

According to Horowitz, viewers may also see other characters from "Frozen," such as Anna and Olaf featuring in Season 4.

He said, "We would be very disappointed if Elsa was the only one from that world that you saw."

While the producers promise a "drama and crisis" between Adam and Emma, we are also likely to see Robin Hood returning to "Once Upon A Time" Season 4. In addition, we may also see Belle (Emilie de Ravin), Rumple (Robert Carlyle), Neal (Michael Raymond-James), and Zelena (Rebecca Mader) returning to the hit show.

The rumor mill is agog with speculation regarding who will be cast in the role of Elsa. As of now, the preferred choice seems to be Elizabeth Mitchell. According to the producers, "Lost" alums Elizabeth Mitchell and Josh Halloway may also join the next season.

"We love those guys so much," Horowitz said in the interview.
