Paramount Pictures and Marvel Entertainment have premiered the first official movie poster for Jon Favreau’s Iron Man 2 on Yahoo. A poster usually means that a trailer isn’t far off. The new poster plays off the number 2 and features Iron Man back-to-back with War Machine.  Favreau previously hinted on his twitter account that we might see the first trailer for Iron Man 2 attached to Guy Ritchie’s Sherlock Holmes, which hits theaters on Christmas Day. Check out the full poster below.

Here is what we know about the film so far:

• Sam Rockwell plays a fast-talking weapons manufacturer named Justin Hammer, “who fancies himself the next Tony Stark”. He sells Stark the weapons he uses to construct War Machine.
• Mickey Rourke plays Russian criminal Vanko, who creates his own battle-suit while incarcerated in a Soviet prison.
• Whiplash’s suit “shoots devastating, whip-like beams.”
• Hammer and Whiplash join forces to take on Stark/Iron Man.
• Scarlett Johansson plays Russian superspy Natasha Romanoff (aka the Black Widow), who is hired as Stark’s assistant which inevitably sparks romantic tension between Stark and former assistant Pepper Potts (Gwyneth Paltrow), who’s been promoted to CEO of Stark Industries.
• Tony is trying to learn more about his father’s mysterious past, specifically the Stark Expo, which must “play a major role in the energy crisis, which is a chief issue in the film.”

Iron Man 2 will hit theaters on May 7th 2010.
