The Dark Knight Rises , The Avengers and Superman: Man Of Steel all have armies of fans posting pics and YouTube videos from the shoots. With G.I. Joe 2: Retaliation it's an inside job, as Dwayne 'The Rock' Johnson tweets an image of himself from his first day's shooting.
Director Jon M. Chu ( Justin Bieber: Never Say Never - no, really) has taken his cast to New Orleans and according to Johnson it's pretty hot there right now.
“1st day of shooting. 110 degrees. Bring It,” is the simple message The People's Champion posted with the image.
Johnson plays Roadblock in a film that also stars Channing Tatum, Ray Park and Walton Goggins.
G.I. Joe: Retaliation opens in the US on 29 June 2012 with a UK release date still to be announced.
