I remember watching this film ages ago, and I can't remember who is in it and what it is called!! GRR! So here is what I can tell you about the film: This guy's wife and kids are pulling out of their and she loses control of their car and they are all killed. The guy is into Wild West photos and he has a photo of a Wild West dude with a gun, but the gun is a modern one. Some people from the future come back to the present, and he goes with them to the Wild West times. The end of the film goes like this: The guy is put to a few minutes before the accident which kills his wife and kids, and he prevents the accident from happening.
Any help would be very much appreciated cuz this is driving me mad!!
Apparently it's out of production but if you go to Amazon.co.uk you can put an order in for it. You could also try that with e-bay under "wanted items"
