Oscar-winning actor Charlton Heston says has been overwhelmed by the outpouring of concern since he announced last week that he has symptoms consistent with Alzheimer´s disease. Heston tells the Los Angeles Times that he has received calls from President Bush, former First Lady Nancy Reagan and Sarah Brady, chairwoman of the Brady Campaign to Prevent Gun Violence. Heston, who won a best-actor Oscar for “Ben-Hur,” says he has no plans to retire from acting and already has a movie project lined up for the fall. Heston also has plans to hit the campaign trail. As president of the National Rifle Association, Heston will campaign this fall on behalf of Republican and Democrats who share similar beliefs.
