I remember seeing this TV movie as a child and really enjoying it. I wish it would show up again so I could compare it to the series it fostered.
This is the pilot that ABC passed on. Apparently, they thought the movie to be a little too Maverick-like (a reviewer at the time actually described Davis's lazy student turned drifter to be a cross between Maverick and another Warner Brothers cowboy, Sugarfoot) and wanted a little more action/brawn and a buddy relationship.
Exit Roger Davis, for the time being. Enter Ben Murphy and the second successful pilot, now called "Alias Smith and Jones".
