Will there be a season 4? And if there was, would Nina be in it?

They have not yet decided, yet written/filmed, if there will be a season 4. However, Tasie Lawrence (actress of Mara) tweeted that if there is enough demands for a season 4, that they will make one, but Tasie will not be on House of Anubis so this means that plus than likely Mara will not be on House of Anubis.

As for if Nina will be in season 4, it's not likely. Natalia Ramos (actress of Nina) a dit that she no longer wants to play the part of Nina (at least this is what I've heard, IDK if that's true). If it is true, then Nina will no longer be on the show. Since Nina was not on season 3, then she may not be in season 4.

The good news is that there WILL be a movie! Alex Soyer (Actor of Alfie) commenté on a tweet that asked if there will be a movie saying, "IDK when it will air". So unless Alex is lying, there will be a movie but the rendez-vous amoureux, date is unknown. The odds of Natalia (Nina) being in the movie is not likely and the movie will be Tasie's last appearance on the show, and plus than likely Mara's?
