Dale Earnhardt was one of the greatest drivers in NASCAR history. Here's what sets the latest documentary about him apart from others.

It's a massive weekend for NASCAR with the Coca-Cola 600 at Charlotte Motor Speedway and the release of a documentary about the legendary Dale Earnhardt Sr. Why it matters: The Earnhardt family is racing royalty with deep Kannapolis ties and " Earnhardt " introduces a new generation of fans to a racing icon.

Teresa Earnhardt has often been referred to as the "Wicked Witch of the South" in NASCAR circles. The ugly nickname is the result of her involvement in various family and business disputes, particularly with Dale Earnhardt Jr., including the No. 8 trademark, which he got earlier this year after Teresa unexpectedly surrendered the rights to it.

Teresa was the third wife of Dale Earnhardt, and the stepmother to Dale Earnhardt Jr. And when Earnhardt tragically lost his life in the final turn of the Daytona 500, Teresa suddenly inherited another role as NASCAR team owner and executor of all things Dale Earnhardt.

While Dale Earnhardt Jr. is all in for the possibility of a points-paying NASCAR Cup race at one of his favorite racetracks, North Wilkesboro Speedway, you can count Kyle Petty as being on the opposite end of that conundrum.

Dale Earnhardt Jr. shares the lingering frustration of knowing his wife Amy will never have the chance to meet his father, Dale Earnhardt.
