There have been many whispers about the possibility of a follow-up to 2001’s hit comedy Zoolander, but one casting rumour seems to be solidifying. According to MTV, the film’s original star Ben Stiller wants British model Cara Delevingne to play a part.
Stiller was being interviewed to promote the third instalment of the family-friendly movies series Night at the Museum: Secret of the Tomb when he was asked about the existence of a sequel. He replied “There is a script, I won't deny there's a script, and there's been a reading of the script - but it hasn't yet been fully formulated.”
