Cassidy was nominated for the Academy Award for Best Film Editing and for an ACE Eddie Award for Into the Wild (directed by Sean Penn - 2007). In 2012, he was nominated for his second Academy Award for Best Film Editing for Silver Linings Playbook, which won the Eddie and the Satellite Award for Best Editing.
