Jeremy Irvine & Lily James Relax During Takes Of ‘Mamma Mia 2’ In Croatia

Jeremy Irvine and Lily James took a break from filming Mamma Mia: Here We Go Again to relax on a boat in Croatia.

JEREMY IRVINE & LILY JAMES RELAX ON SET OF MAMMA MIA 2

Irvine plays the young version of Pierce Brosnan‘s character Sam Carmichael in the sequel to the 2008 musical hit, while James plays the a young version of Meryl Streep‘s Donna. The film jumps around in time to look at various points in the charaters’ lives and relationships.

Fans will recall that Sam is one of the three potential fathers of Donna’s daughter Sophie (originally played by Amanda Seyfried). The other possibilities are Bill (Stellan Skarsgård) and Harry (Colin Firth). Brosnan, 64, and Streep, 68, are expected to reprise their roles.

The story appears to kick off on the Croatian island of Vis, where young Sam and Donna’s relationship is thought to have begun. Between takes, it appears the co-stars were enjoying time together out on a boat in the sea.

James posted a photo of herself, Irvine, and Josh Dylan on the back of the motorboat, with the caption, “this isn’t work #mammamia2.”

Irvine posted the same photo (with a noticeably different filter) but with the caption, “The ‘commute’ to work each morning for #mammamia2 #worknotwork #mammamiamovie.”

The film is slated to hit theaters on July 20, 2018.
