At least according to the Twitter account UK Film Premieres, which seems to be legitimate from what I can tell. According to this Tweet, the G.I. Joe: Retaliation UK film premier will hit in February, 2013 and will have Bruce Willis, Channing Tatum, and Adrianne Palicki in attendance.
Obviously this hasn’t been officially announced by Paramount yet, but some quick research of past Tweets from this account seem to indicate a level of legitimacy, so we’ll go with it for now.
And with a sudden jolt, you realize just how close we are to the release of the film. Under 90 days until it hits American theaters. Holy wow!
