As expected, the first batch of presenters seem to be made out of tradition. Last year’s winners Jeff Bridges and Sandra Bullock have been announced (they will be presenting this year’s opposing Lead Acting trophies) along with Oscar nominee Oprah Winfrey and Oscar winners Halle Berry and Marisa Tomei. The full release is below. As soon as I can find the time to update it, the sidebar on the right will also feature a display of presenters announced.
