Yeah, if I'm not mistaken, there already was an Abe screenplay that had been written.
I did enjoy MO and SW immencely, but AO and AE will always hold a special place in my heart because they were the most original ones out of the entire series, in my opinion. If there was to be a movie, I hope that it would be about Abe and the old cast of characters maybe with a few new ones as well.
