I think Michael Hall from Dexter would make a great Jack ... he's got that normal guy, blend-in-ability look. I'd hate to see all the work go into a Repairman Jack movie with someone who just doesn't fit the bill. Like with the One Shot movie from the Lee Child book, they're using Tom Cruise as Reacher and he is so NOT Reacher it's ridiculous.
We are each of us angels with only one wing, and we can only fly by embracing one another. ~Luciano de Crescenzo
