Here is why Michael Cera isn't part of 'Barbie' stars' WhatsApp group

Hollywood star Michael Cera said that he wasn’t part of his fellow Barbie stars’ WhatsApp group chat.

The Superbad actor plays doll Allan in Greta Gerwig’s new film about the Mattell creations alongside Margot Robbie and Ryan Gosling, but he told a popular magazine that he wasn’t able to join in their off-set chat because he has a retro flip phone, according to reports.

"I don’t have an iPhone myself. I have a flip phone," the 35-year-old confessed.

If he did have a smartphone, he might not be in the chat anyway, because his character Allan "is sort of in his own little world."

Allan is a real doll in the Barbie line-up and was first introduced by Mattel in 1964. In the Barbie novels, the doll started out as "Ken’s Buddy" and was romantically linked to Barbie’s best pal Margaret "Midge" Hadley.

Michael added about the Barbie film’s 39-year-old director: "Greta’s gift for me when I arrived (on set) was a picture disc of NSYNC’s No Strings Attached." And according to the actor, it "felt like somehow a real guiding light in the backstory of this character."

Margot previously gave a hint of the kind of deep chat about the flick Michael may have missed. She said she has become convinced Barbie film tackles the concept of a power "hierarchy." 

She said at the European premiere of the film at Cineworld in London’s Leicester Square on 12 July, "To really do something unexpected and fun and clever and silly on such a big scale, it feels like a very unique opportunity."

"Barbieland feels like a female utopia. But you do, by the end of the film, see the flaw in that — I mean, a hierarchy in anyone's power is not necessarily the best thing," she shared. 

"But it is fun — it's very pretty."

The film sees Barbie’s perfect pink world of fashion, grooming and parties brought crashing down when she finds herself having dark thoughts about death. 

She finds cellulite on her perfect legs and her famous feet suddenly become flat — and with the encouragement of the wise 'Weird Barbie' played by Kate McKinnon, 39, Barbie embarks on a journey of self-discovery in the real world, with Ken joining her for the ride.

Also at the Barbie premiere was singer Dua Lipa, who plays Mermaid Barbie in the film. There were also co-stars Will Ferrell, 55, Issa Rae, 38, and Hairi Nef, 30, who helped make up the ten Barbie’s and four Ken’s in the project.
