Known for her role as Detective Grace Hanadarko on “Saving Grace,” Holly Hunter was almost ready to show off her theatrical chops in the Off-Broadway show, “The Vandal.” As it seems with many celebrities who must vacate a role, details are sparse. In Hunter’s case, “scheduling conflicts” were the reason she could not go on. Luckily, with Deirdre O'Connell taking over the role, the production was considered a success without Hunter, and the run was extended until March 3.
