I love the plots of the older movies. What's more, I love the older actors/actresses at work in what they do best: plots of older movies. Now, "Killshot" is not exactly an "old movie" at all; however, it has all the components of an "old movie": Great plot and great people doing the acting and, apparently, the directing and everything else to boot.
I have been a long-time fan of both Diane Lane and Mickey Rourke. I think I would rather watch and listen them read their grocery lists than watch a modern-day movie with a bad plot and poor acting. Elmore Leonard also writes good books. Man! Put all of that together along with some really decent supporting actors and you have the ingredients for 95 minutes of great suspense. And they pulled it off in an excellent fashion!
I won't give away more of the plot than the trailers show. Suffice it to say that they managed to do in 95 minutes what a lot of today's films (and I like today's films, too) can't manage to do at all: Keep the suspense, action, and thrills going without having to show someone's brains splattered all over the room. There's blood, but then, there's BLOOD! The director managed to shrug off the need for gore and concentrate on the plot instead. Good for the director! The actors/actresses managed to do everything they needed to do without over-acting their parts. This is, in my opinion, what a group of actors who have been in the business for awhile can do with almost perfection. This group managed that.
If you want to watch parts of bodies, knife-slicing, and general gore, watch something else. If you want to be entertained and be nervous, watch "Killshot".
