Watch: Cher returns to the big screen in Mamma Mia 2 trailer

The first trailer for the highly anticipated sequel to Mamma Mia has leaked online.

After the massive success of the first film, the Abba-themed musical is set to return to the big screen in 2018 with the entire original cast, as well as a few new surprises.

The film will feature legendary screen icon Cher, who previously revealed that she had been rehearsing dance numbers in preparation for her cameo.

The movie will be Cher’s return to the big screen after several years as the star has been busy touring and developing a Broadway musical based on her life.

Meanwhile, earlier this week Amanda Seyfried revealed that she was initially hesitant to sign on for the sequel.

Mamma Mia: Here We Go Again! is set for a July 2018.
