Director Moisés Kaufman told the New York Times that negotiations are currently underway with producers Robyn Goodman and Kevin McCollum for a spring 2011 Broadway bow.

In Bengal Tiger at the Baghdad Zoo, according to CTG notes, "the lives and, in some cases, the afterlives, of two American soldiers, an Iraqi translator, the ghosts of Saddam Hussein's sons Uday and Ousay, and a Bengal tiger all intersect in a surreal, darkly humorous and gently balanced view of war and its aftermath."

Williams would play the role of the tiger who comments on the situation. Kevin Tighe played the part in Los Angeles.

"There is a great deal of intelligence and sarcasm and humor in that character, who has a bird’s eye view of us mortals," Kaufman told the Times. "There is something about the keen intelligence and unblurry eye of the tiger that fits when I think of Robin."

The play was a finalist for the 2010 Pulitzer Prize for Drama, along with The Elaborate Entrance of Chad Deity by Kristoffer Diaz and In the Next Room or the vibrator play by Sarah Ruhl.

Actor-writer-comedian Williams, who became known during his work in "Mork & Mindy" — a spinoff created from a guest spot on "Happy Days" — is widely hailed for his madcap improvisational humor in movies such as "Good Morning, Vietnam," "Aladdin," "The Birdcage," "Mrs. Doubtfire" and "Death to Smoochy," among others. Williams has often taken on dramatic roles as well in such films as "The Fisher King," "Awakenings," "Insomnia" and his Academy Award-winning turn in "Good Will Hunting."

On stage the actor may be remembered for his performance as Estragon opposite Steve Martin's Vladimir in the Mike Nichols-directed production of Samuel Beckett's Waiting for Godot.
