Dwayne Johnson is apparently an avid Twitter user. A couple months ago we got our first look at the actor in character as Roadblock in G.I. Joe 2: Retaliation via his Twitter account, and today he’s given us another look at him in character through a photo and a video he shot onset. It's not much, but he teases a major action sequence being shot near him. Furthermore, you might be able to spot a familiar face from the Collider community in the set photo.

Hit the jump to check out the image and video. Directed by Jon Chu, the film also stars Bruce Willis, Channing Tatum, Adrianne Palicki, D.J. Cotrona, Byung-hun Lee, Ray Park, RZA, Joseph Mazzello, Elodie Yung, and Walton Goggins. G.I. Joe 2: Retaliation opens June 29, 2012.
