I would love to see an Arthur movie, maybe not live action, maybe stay with the 2D animation. I posted a topic about possible Arthur Movie ideas on this board. I think a movie would do great in theaters.
Arthur has a huge fan base with little kids, teenagers and adults so it would make a great deal of money. It is also the third longest running PBS Kids TV Show behind Seasme Street and Barney and those two had movies that came to theaters.
So please, whoever is reading this, please write Cookie Jar Entertainment or Marc Brown a letter saying that Arthur would make a great theatrical movie because that's what I am going to do write now and the more people who write, the more of an Arthur Movie will come!
