Robert Downey Jr., Tina Fey in talks for 'Master Mind'

Ben Stiller producing DreamWorks Animation project

Robert Downey Jr. and Tina Fey are in negotiations to lead the voice cast for DreamWorks Animation's superhero lark "Master Mind." Ben Stiller is a producer on the movie through his Red Hour Films.

The satiric film, with a screenplay by Alan J. Schoolcraft and Brent Simons, concerns a brilliant superhero villain who loses his life's purpose when he accidentally kills his good-guy nemesis. DWA plans a Nov. 5, 2010, release (though the title might change).

DWA had a banner year in 2008 with its releases "Kung Fu Panda" and "Madagascar: Escape 2 Africa" (also starring Stiller), which together have grossed more than $1.2 billion worldwide. The Jeffrey Katzenberg-led company also has "Monsters vs. Aliens" in theaters in March, "How to Train Your Dragon" and "Shrek Goes Fourth" in 2010, and a "Kung Fu Panda" sequel scheduled for 2011.

Paramount, which distributes DWA's output, has its own animated feature, "Rango," starring Johnny Depp, in production for a March 2011 release.

Fey, repped by Endeavor and 3 Arts, most recently starred in the Universal comedy "Baby Mama" and is attached to star in the Fox comedy "Date Night" with Steve Carell. She continues to produce, write and star in "30 Rock" on NBC.

The Endeavor-repped Stiller has "Night at the Museum: Battle of the Smithsonian" coming in May and most recently co-wrote, directed and starred in the DreamWorks comedy "Tropic Thunder."

Downey, repped by CAA, has "Sherlock Holmes" and "Iron Man 2" in production this year, and "The Soloist" hitting theaters in April. He did an Oscar-nominated turn in "Tropic Thunder" last summer.
