The giant robots are, of course, the stars of the "Transformers" universe, but there certainly doesn't seem to be a shortage of flesh & blood actors signing on for the massive production. The newest names added to the call sheet are Tyrese Gibson ("Four Brothers"), Rachael Taylor ("Man-Thing"), and Amaury Nolasco ("The Benchwarmers").

The latest cast additions come from DarkHorizons and The Hollywood Reporter.

"The Transformers," which will come from screenwriters Roberto Orci and Alex Kurtzman, director Michael Bay, and executive producer Steven Spielberg, already has a pretty stacked cast list. The newest trio join Shia LaBeouf, Bernie Mac, Jon Voight, Josh Duhamel, Michael Clarke Duncan, John Turturro, a few others, and a bunch that probably haven't been announced yet. Plus all those giant robots who morph into vehicles.
