Iron Man 2 finished filming and entered post-production way back in July, so it was expected Marvel would give us a trailer sometime in the near future. Well earlier today director Jon Favreau retweeted a message from someone on Twitter, and it hinted that we could see the first trailer with Sherlock Holmes:
RT @Ann_Howard: @Jon_Favreau PLEASE tell us the trailer is coming soon – w/Sherlock Holmes, perhaps??
This makes sense. Sherlock Holmes stars Robert Downey Jr. after all. Expect the first Iron Man 2 trailer online around December 25th.
