Although the whole fandom was already aware of this casting choice, today it was made official by Summit Entertainment that Winslet will join the cast as the leader of the Erudite faction, Jeanine Matthews. Summit earlier released a short statement regarding the news and I’m sure we’ll get more information very soon!

Update! Veronica Roth’s Reaction to the news:

Okay, so you may have seen/heard rumors of this already, so it’s not exactly new news, but it is Officially Official, which means that I can tell you my thoughts.

KATE WINSLET has been cast as Jeanine Matthews!

What can I say? When I found out, I was floored. I grew up watching Kate Winslet in movies, whether it was Titanic or Eternal Sunshine of the Spotless Mind or The Reader, and she is an incredible actress, and I am sure that she will be extraordinary as Jeanine. I’m excited to see the complexity and depth she’ll bring to the role.

That was me containing my fangirling.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(That was me not containing my fangirling.)

She’s not the only one fangirling, right initiates?
