From WWE.com:

It was a sight many fans never thought they would see again, until now. Bret Hart and Vince McMahon met face to face today before shooting began for the upcoming DVD chronicling the Hit Man’s career.

During shooting, McMahon and Hart both talked about Bret’s beginnings, SummerSlam 1992, the historic Owen Hart-Bret Hart rivalry, Stone Cold Steve Austin, the infamous Montreal incident, Bret’s jump to WCW and much more.

Afterwards, the Hit Man said he was “happy with how everything went today,” regarding the Bret Hart-WWE joint production.
