Exclusive: Dwayne Johnson's Emotional Moment

Dwayne Johnson plays a tough dad forced to drive for a ruthless drug cartel to save his son in the gritty action-thriller Snitch, on DVD and Blu-ray June 11, but in this exclusive clip for ETonline, The Rock shows his softer side by explaining that the tears came naturally for an especially emotional scene -- and it was almost ruined by a continuity error!
Based on a true story, Snitch finds Johnson as a concerned father faced with a dramatic choice after his teenage son is wrongly accused of a drug distribution crime. With his boy facing a minimum prison sentence of 10 years, the desperate and determined Johnson makes a deal with the U.S. attorney to work as an undercover informant and infiltrate a dangerous drug cartel (whose key player is played by Benjamin Bratt). Willing to risk everything to free his son, can Johnson make it out alive?
Snitch also stars Susan Sarandon and Barry Pepper and is directed by former stunt master Ric Roman Waugh.
