"For a very long time, we had always hoped to work with Don Mischer. His talent and reputation are unsurpassed and we're so happy he will be our collaborator on the 85th Academy Awards," telecast producers Craig Zadan and Neil Meron said in a statement.
This will be Mischer's third consecutive year as director of the Oscars. He has served as producer as well as director on the 83rd and 84th Academy Awards and was nominated for Emmys for directing both shows. Last year's Oscars received eight Emmy nominations, the most for any TV special.
"I am so very excited to be directing the Academy Awards again this year and to be working with creative producers like Craig and Neil. All of us at Don Mischer Productions are also thrilled to be producing the Oscar pre-show, and most significantly to continue a wonderfully gratifying relationship with the Academy," said Mischer.
In addition to the Oscars, Mischer has directed several Super Bowl halftime shows, the Kennedy Center Honors and television specials featuring musical performers such as Barbra Streisand, Justin Timberlake and Yo-Yo Ma.
He will executive produce the Emmy awards, which take place September 23.
Academy Awards for outstanding film achievements of 2012 will be presented on February 24, 2013, at the Dolby Theatre at Hollywood & Highland Center.
The Oscar presentation will be televised live in more than 225 countries worldwide.
