A former executive claims Disney had to cancel plans for a fourth movie in the "Aladdin" series because Robin Williams' will prevents the company from using his name, taped performances or voice recordings for 25 years after his death.

The unnamed executive told New York Post that the actor recorded more than enough voice work to be used in future installments.

“When he was on form, the hyperactive motormouth we love from ‘Good Morning Vietnam’ and ‘Mrs. Doubtfire’ was making 30 jokes a minute,” the executive said.  “Now, because he insisted on a final say on such material, [the material] will remain in the vaults.”

Williams' widow, Susan, recently revealed that the 63-year-old actor was suffering from Lewy body dementia before his suicide.
