I like Rambo and Tears of the Sun. Mercenary snakes, though. Sir Bronn of the Blackwaters Arizona Black Rattlesnake, Snake Pliskins Snouted Cobra, Ryan Reynolds Jameson's Mamba, Storm Shadows Coastal Taipan, Adrien Brody's Sharp-Nosed Viper in Predators. Daniel Craigs Western Diamondback Rattlesnake, Jean Claude Van Dammes Eyelash Pit Viper, I also like Brendan Fraser & Dolph Lundgren. I can see Bushmaster and Russells Viper styles. I'm the Malayan Pit Viper.
Only cowboy/outlaws that I know of are Malabar Pit Viper, Northern Pacific Rattlesnake, and Death Adders.
