Kristen Bell Reunites Old Classmates to Recreate Their High School Musical in 'Encore' -- Watch! (Exclusive)

By

Kristen Bell is helping high school performers relive their glory days!

The 37-year-old actress' new ABC special, Encore!, will reunite a group of former classmates to recreate a performance of their old musical theater production -- and ET has your first look!

The show will see a cast come together after 20 years to reprise their roles in their original high school production of Into the Woods. They will only have seven days to remember their lines, their choreography and take the stage. The memories, the rehearsals and the labor -- literally, in the case of one pregnant performer -- will all be documented leading up to their on-stage "encore."

"We are into the weeds," one cast member says in ET's exclusive sneak peek, while another one tells the camera, "Help us!"

Bell also serves as executive producer on the show, alongside creator and executive producer Jason Cohen and EPs Alycia Rossiter, Will Gluck, Richard Schwartz, Jim Roush and Chris Wagner.

The actress was last seen in A Bad Moms Christmas and will reprise her role as Anna in the Frozen sequel. Her co-star Idina Menzel told ET earlier this month that they have begun production on Frozen 2, which is expected to hit theaters in November 2019.

Hear what she had to say in the video below.

Encore! premieres Sunday, Dec. 10 at 10 p.m. ET/PT on ABC.
