Oscar winner Charlize Theron is set to add some star power to Fox's "Arrested Development" when its third season debuts next month.

Theron has signed on to guest star in five episodes of the series, playing a British woman who becomes the love interest of "Development" star Jason Bateman. Theron will debut in the second "Development" episode of the season, following its Sept. 19 premiere.

Theron earned her best actress Oscar last year for her portrayal of a serial killer in "Monster." She's also up for Emmy honors this year for her co-starring role in the HBO biopic "The Life and Death of Peter Sellers," in which she played actress Britt Ekland.

On the feature side, Theron just wrapped production on "Aeon Flux," a live-action adaptation of the MTV animated series. She will be seen opposite Frances McDormand and Sissy Spacek in Warner Bros. Pictures' drama "North Country" in the fall. Theron's other recent credits include 2003's "The Italian Job" and 2004's "Head in the Clouds."

Theron is repped by manager J.J. Harris of One Entertainment.
