From what I have seen, it looks doubtful that there will be any more Eloise movies. Now this just illustrates Disney's bad decisions. I am not a huge fan of Eloise but my wife is and a lot of her friends and their children are as well. This can't cost hardly anything to make and it does very well with young girls audiences. SO what in the world is their rpoblem? They already have the cast and stories set up from the books so it would simply be a matter of getting Juile Andrews to do it.
Disney has made a ton of bad decisions in the past few years.
