Bradley Cooper is taking his Oscar-nominated “Silver Linings Playbook” and the issues it raises about mental health to Walter Reed Army Medical Center in DC today. Cooper’s screening and discussion have been organized in conjunction with Give an Hour, volunteers who provide returning vets with free services. Cooper will also appear on Chris Matthews’ show. His co-star Robert De Niro will have his hand- and footprints immortalized in cement outside Grauman’s Chinese Theatre next month.
