Dwayne “The Rock” plays Beck, a nice-guy knee breaker who’s sent after an indebted explorer (Seann William Scott) in the Amazon jungle. All of it is mildly amusing and fairly innocuous until the climax, when the previously gun-averse Beck reluctantly grabs a huge weapon in each hand and then rises into the melee like a phoenix from ashes. It’s treated as a redemptive moment – salvation by shotgun, if you will – and yet another troubling example of Hollywood gun worship.
