Warner Brothers apparently didn't want to go too far (read "spend too much") to find an actor to play the patriarch of our intrepid Maverick brothers. James Garner does double-duty as Bret and "Pappy" in an amusing story that also reveals that Maverick blood is thicker than money. The plot involves news of Pappy's forthcoming marriage that the brothers--and everybody else--oppose, only to reveal a scam within a scam.
It's difficult to get past the fact that Garner is playing two roles--you find yourself looking at his makeup and thinking of how that could have been done better. It tends to obscure a clever plot that has Pappy quoting his Pappy. Jack Kelly is thrown a bone with a cameo appearance as Pappy's brother, which gives some symetry to the whole premise of the Maverick brothers, two generations worth.
I just struggled with the poor casting/makeup choices of Garner as Pappy.
