Louisiana. Bill Nighy doesn't purr. Bill Nighy 'hmmmm's' through thin lips and then shrugs you a snorting guffaw. He then regains his wiry composure whilst his hair falls back into the form it was disturbed from. His eyes then pierce into you from behind those thick black specs, teasing out the undying affection you've held for the cad all your life. So yes, although I've never met either fellows, this Jah Lush certainly sounds like a fitting substitute for a pet Nighy.
