I came across "Duel" at the local WalMart this last weekend. $13.00
Includes some extra features.

I picked it up on release day. One of the best TV movies ever. '71 was a great year for TV.

Indeedy!

First time I saw it was an afternoon rerun on ABC. I was totally transfixed! Masterful filmmaking! Then Mom came in and sat down right near the end and started in with "Why is the truck chasing him? Who's in the truck? What did Dennis Weaver do? yadda yadda..."

Oy.
