ET has shared a first look at ABC's one-hour musical event special ENCORE. Check it out below! The show premieres on SUNDAY, DEC. 10 (10:00-11:00 p.m. EST). In ENCORE, executive producer Kristen Bell, who also appears, reunites the cast of a high school musical and asks them to perform it again twenty years later. Each former student reprises their role from their original production of Stephen Sondheim and James Lapine's Tony-winning musical, INTO THE WOODS, under the tutelage of Broadway directors, choreographers and voice coaches.

"Encore!" was created and is executive produced by Jason Cohen, with Kristen Bell, Alycia Rossiter, Will Gluck, Richard Schwartz, Jim Roush and Chris Wagner, also serving as executive producers. Anthony Carbone is editor and executive producer.

Kristen Bell reprises her role of FROZEN's Princess Anna in the upcoming Disney featurette OLAF'S FROZEN ADVENTURE, hitting theaters this November. She can currently be seen in the NBC comedy series THE GOOD PLACE and will star in Disney's upcoming sequel FROZEN 2. The actress made her Broadway debut in 2001's THE ADVENTURES OF Tom Sawyer and starred in the 2002 revival of THE CRUCIBLE.
