The Mamma Mia 2 - aka. Mamma Mia! Here We Go Again - first look footage and poster are here, with the trailer arriving tomorrow. Mamma Mia! Here We Go Again is ramping up the ABBA soundtrack once more to transport us the musical Greek island from the previous stage musical-turned film.

Mamma Mia! Here We Go Again follows the popular 2008 musical, and features the return of the the original cast along with some new faces thrown in the mix. While we have no clear indication of the plot, the sequel looks to be playing with some time-jumps, judging by the casting of younger versions of Donna and her three lovers: Sam, Bill and Harry. When the trailer arrives tomorrow, we should have a better idea of what the story is about.

Meryl Streep, Amanda Seyfried, Pierce Brosnan, Colin Firth, and Stellan Skarsgard are among the many returning cast members. Lily James (Baby Driver-fame) will be playing Young Donna and Jeremy Irvine, Hugh Skinner, and Josh Dylan will be playing younger versions of Sam, Harry, and Bill, respectively. Judging from the first look, the new cast members fit right in with the sun-drenched beaches and elaborate dance numbers. Along with these newer, younger faces, the cast will also be joinied by Andy Garcia and none other than Cher, whose last appearance on-screen anywhere was 2010. Cher was reportedly supposed to join the original film, but had to back out due to prior tour commitments. You can check out the film's poster, below:

Here We Go Again picks up from the wonderfully dumb Mamma Mia (2008), where Sam (Pierce Brosnan), Harry (Colin Firth), and Bill (Stellan Skarsgard) each kind of battle it out in song over the privilege to walk his daughter down the aisle at her wedding. Here's the thing though: no one actually knows who the father is! What fun! Meryl Streep plays Donna, mother to Sophie, who at one point had a romantic relationship with each of these men, and Sophie (Amanda Seyfried) has invited all of them to her wedding in Greece to figure out which one is her father. All along the way, everyone's singing ABBA songs, which is kinda fun. With the proposed time-jumps, we should expect to see the early formations of Donna's relationships with these men.

While the original film wasn't critically acclaimed, it was commercially successful. Mamma Mia! became the fifth-highest grossing film of 2008, and the highest grossing live-action musical of all time, until Beauty and the Beast changed that earlier this year. Despite critical reviews, the original Mamma Mia! is a good bit of fun, with a good amount of ABBA songs re-imagined by the cast. Here's hoping Young Sam is a better singer than Older Sam.
