Lads, I posted something similar on PowWow; if you're interested in some great DVDs with the odd bit of dangerous game mixed in, check out the vintage Fred Bear films which have just been released on DVD at 3Rivers....in particular, I must mention the DVD called "Prairie Pronghorn and Bwana Bowman" in which Bill Negley stars in the latter episode, making a great (and clear) shot on his first (of five confirmed) bull elephants. It's just marvellous!
I have not seen the others, but I did see the one you just mentioned.
You are right, that footage of Bill Negley is amazing. Both Bill N., and his guide seemed to pull that 100 pound recurve pretty easily! Yikes.
Just listening to the narration is entertaining.
