Fans Think Another Celebrity Should Have Played Barbie

But not everyone is happy with the casting for the hotly anticipated film, set for release next year.

In a first-look photo of Barbie, Robbie can be seen sitting in her Barbie-pink convertible dressed all in blue with a matching headband and bracelet.

Meanwhile, in separate shots of Robbie and Gosling filming, the 32-year-old can be seen dressed in a fluorescent leotard and cycling shorts as the pair roller-skate around a beach.

While many fans are in agreement that Robbie looks fab as Barbie, others believe a different actor should have been cast - specifically, Amanda Seyfried.

Writing on Twitter, one person said: "I can't stay silent any longer... wish amanda seyfried was barbie."

While another said: "Someone said Amanda Seyfried as Barbie and now I’m thinking."

And a third added: "As much as I love margot robbie, I gotta agree amanda seyfried would be such a perfect barbie."

And a fourth wrote: "I may be alone here... But, I think Amanda Seyfried and Zac Efron would make the perfect people to play Barbie and Ken."

Others totally disagreed, however, with one commenting: "I LOVE Margot Robbie as Barbie... Love Amanda seyfried too but don’t do my girl Margot like this."

While another said: "Margot robbie is the perfect casting for barbie!!"

And a third added: "I still can’t get over how perfect Margot Robbie is as Barbie."

"I’m SO excited, margot robbie looks so good and is the perfect actress as barbie!" said another.

In a first-look photo, Gosling has had a serious Ken makeover, with bleached blonde hair, a glowing – and slightly orange – tan and a sleeveless denim jacket showing off Ken-doll abs beneath.

Posing next to a bright Barbie-pink pillar, Gosling is also wearing light wash denim jeans with 'Ken'-scribed underwear slightly on show.

While he certainly looks the part, some believe Zac Efron could have been a better fit, with one adding: "I’m sorry, I love Ryan Gosling as much as the next girl. But Zac Efron has been living his life as a Ken doll since his Troy Bolton days. The man CRIED when he got to eat carbs for the first time in 6 years. That’s my Ken."

Others totally disagreed, however, with one adding: "Ryan Gosling as Ken in #Barbie is actually perfect."
