He produced Bluth's earlier films An American Tail and The Land Before Time. He should produce Dragon's Lair too.

I don't get why him and Bluth fell out in the first place. That being said, I'd like to see him produce the Dragon's Lair movie.

I think Spielberg stopped working with Bluth after Spielberg insisted that The Land Before Time be recut, against Bluth's wishes. Spielberg in particularly softened Littlefoot's mother's death, fearful that keeping it too violent would have scared kids.
And as much as I like Don Bluth, so many of his films in the 90's were such flops that he's not exactly commercial anymore. Titan A.E. was an immense box office disaster. If his films were still profitable, he wouldn't have to be going to Kickstarter for help. That's the sad but honest truth.
