Joseph Vacher or Albert Johnson (Film potential)

Note:This thread is not made to glorify the murderers.

Which film would be better (Please give a reason)?

A film featuring Joseph Vacher story

Or

A film featuring Albert Johnson story

Pilasy:La Voix d'un homme

Albert Johnson would be a much more appealing movie I think. A manhunt through the Canadian North for a madman with no name. Whop May was part of it, too. Interesting.

Edit: Holy cow. The only fatality in this manhunt, aside from Johnson, was Millen, the constable who first made contact with him. Chilling. This stuff is more interesting the more I read of it.
