I thought about using a laminate floor. It's a good idea, but the thing that kills is is the texture they put on it. I assume they do this to give it a little more friction. Good for flooring, bad for shuffleboard. Of course, laminate flooring is really just pieces of MDF anyway. I also thought about just using regular wood floor, but then the problem is all the wood filler needed to fill the gaps between boards. Even if you could get them all filled and sanded it would look pretty ghetto when it was done.
One of the advantages of MDF is you can paint it however you like. Movie film is a pretty cool idea. Sounds like it would fit your basement theme pretty well.
Oh, and the Wife Acceptance Factor on the shuffleboard table was pretty high. Everyone seems to like shuffleboard! Unlike my MAME cabinet, which I finished nearly 3 1/2 years ago, and I think my wife has played it for a total of maybe a half hour.
