On his cell phone, James Rhodes has the numbers for O. Stane, H. Stark, T. Stark, J. Storm, S. Storm, and M. Stryker. O. Stane is most likely Obadiah Stane, an Iron Man villain. H. and T. Stark is clearly Howard and Tony Stark. J. and S. Storm are like Johnny Storm and Sue Storm of the Fantastic Four. M. Stryker could be Marcy Stryker, wife of William Stryker, the X-Men villain. This would also mark Stane's first "appearance" outside of the comics.
James Rhodes calls the guards Jake and Elwood... those are the names of the Blues Brothers, Jake and Elwood Blues.
Although this animated film premiered in 2007, it was produced in 2006 according to the credits.
