It is full roll when SVT comes to visit the studio in Sävast.
Agnes Colliander walks around in a yellow t-shirt and red shorts while she plays the role of Ella, "Little Zlatan", who becomes jealous of her uncle Tommy who met a boyfriend from Holland.
The book is written by Pija Lindenbaum and was published in 2006.
What is it like to be an actor?
- It's fun to stand in front of a camera and not be yourself because sometimes it's boring to be yourself, says Agnes Colliander.
She is no stranger to continuing as an actress after the filming is over.
- Maybe yes, but not exactly in a lead role where you are in every single scene as I am now.
Simon J Berger: Glad that we are investing in children's films
Also in the studio is actor Simon J Berger, who plays Ella's uncle Tommy.
- Sometimes you get the feeling that children's culture is considered a little less uplifting than adult work.
For me, it's a bit strange so I'm very happy that you make a real investment in a children's film, he says.
Other requirements for adults and children
Playing against children places different demands than when playing against adults, says Simon J Berger.
- You always work with giving and taking.
With children, a larger part of the work is about servicing their needs or playing them out than with an adult actor.
But it also belongs and it is very fun.
