BEVERLY HILLS, CA – The Oscars will feature special appearances by Academy Award® winner Charlize Theron, Channing Tatum, Joseph Gordon-Levitt and Daniel Radcliffe at the upcoming Awards ceremony.

“We are quite excited to have Charlize, Chan, Joe and Dan join us on the show,” said telecast producers Craig Zadan and Neil Meron. “We are happy to feature them as special guests in our production.”
This will be Gordon-Levitt, Radcliffe and Tatum’s first time appearing on the Oscar show
