It may be a teaser for a trailer and wow does it deliver! In the Skyfall teaser we learn about M’s past coming back to haunt her. Mallory (Ralph Fiennes) in a cool tone confronts M (Dame Judi Dench) over losing a disc with the “identity of every covert agent embedded in terrorist organization across the globe.”
During that dialogue you see 007 (Daniel Craig) is the agent who lost it and then he’s on top of a train. M orders “take the bloody shot” and as assasin shoots James Bond on a moving train and he falls.
…And I freaked out! The trailer arrives tomorrow. Skyfall opens this November.
