What book, cartoon, toy, etc, have you enjoyed that Hollywood has not created a movie out of yet?

Name a few if you would like.

Would you accept or reject it from becoming a feature film? If you accept, why? Do you have any ideas for the plot, characters, or type of film. What actors/actresses would you prefer for the roles and who should direct? If you reject, why? Is it because it is too close to your heart and wouldn’t like for it to be ruined? Or do you think it would just be a bad idea overall?

How long do you think it will be before it will become a movie? Any other thoughts?
