Once a gifted child actor, Haley Joel Osment (The Sixth Sense, A.I.) is now an adult and set to make his Broadway debut. The 20-year old actor will play Bobby in the upcoming Broadway revival of David Mamet's play American Buffalo, alongside the already-cast John Leguizamo and Cedric the Entertainer. The production will have its official Broadway opening at the Belasco Theatre on November 17.
