The actress mentioned the prospect of the stage role while appearing on "Live with Regis & Kelly" Nov. 26.
Set in the world of a Hollywood studio executive, Speed-the-Plow follows a producer who must decide whether to green-light a standard blockbuster drama starring a big name or an adaptation of an obscure apocalyptic novel.
Alba would play the role of the exec's temp assistant with whom he becomes involved. The role was originally played on Broadway in 1988 by Madonna. Gregory Mosher directed that production, which also starred Joe Mantegna and Ron Silver.
Alba has been seen in "Fantastic Four," "Sin City," "Honey" and the television series "Dark Angel." The actress noted her casting in the Mamet play was not definite, but she may be able to fit Broadway into her schedule, especially if an actors' strike by the Screen Actors Guild were to occur in June.
Alicia Silverstone took on the role in a recent Los Angeles revival of Speed-the-Plow. The Mamet work is also slated for a London run starring Kevin Spacey at London's Old Vic in February 2008. Laura Michelle Kelly and Jeff Goldblum have been mentioned as possible co-stars.
