With four days to go until the Oscar show, the bookings are coming fast and furious now.
On Wednesday morning, the Academy and show producers Bruce Cohen and Don Mischer announced three more presenters for the 83rd Oscar show: Best Actor nominee Javier Bardem, Dame Helen Mirren and Matthew McConaughey.
Bardem and Mirren are past Oscar winners, with seven nominations between them. (She has four, and won for "The Queen"; he has three, and won for "No Country for Old Men.")
McConaughey has never been nominated, but has appeared on the Oscar show as a presenter in the past.
TheWrap's full list of announced presenters and performers has been updated.
The Academy and the producers also announced that the Oscar orchestra will be conducted by composer, orchestrator and arranger William Ross.
