Finally, an extended trailer for Skyfall, in theaters October 24.
From the Hollywood Reporter:
Packed with plot details, the Skyfall trailer reveals that M, played by Judi Dench, made the decision to take out her Double-Oh program's agents, but was unable to take down the super-suave Mr. Bond. After a period of living it up in death, Bond returns, to a shaken MI6 foundation and a new source of villainous treachery in Javier Bardem.
