Bust out your bell bottoms, “Mamma Mia!” is getting a sequel!

After all this time, the Mamma Mia! movie is finally getting a sequel —  and the entire original cast will be involved. Everyone is on board, including Meryl Streep, Amanda Seyfried, Colin Firth, Pierce Brosnan, Stellan Skarsgård, Julie Walters, and Christine Baranski.

We know what you’re thinking — will ABBA be involved, too? Yes! According to Variety, the sequel will feature some ABBA songs not used in the 2008 film, and the band will also reprise some “favorites.” Not only that, but all of the original producers, including Judy Craymor, who is the creator of the stage version of Mamma Mia!, have also signed on, so this is going to be HUGE. There’s no word about the plot yet, but it will be set on a Greek island again.
