Most implausible part of the movie?
It wasn't skiing through the jungle or surfing with a motorcycle - it was Vin Diesel seducing countless hot women half his age. And he did so while wearing a jacket that a 70s era pimp would find tacky. Not surprised to see he produced this awful movie. "Ok, here's the scene - I'm going to wear a giant women's fur coat and 20 hotties are going to be overcome with desire."
Donnie Yen was the only thing worthwhile in this train wreck.
And enough with the wise-cracking snipers. It was annoying when Steven Baldwin did it in the Usual Suspects and even worse in xXx.
