While not the best of Flynn's westerns, San Antonio offers appealing players a lavish budget, and plenty of action. It was the Christmas offering from Warner Bros., and, perhaps due to the returning G.I.'s, the highest grossing film Flynn ever made (in its original release). Some good music helps, as does the chemistry between Errol and Alexis Smith. Raoul Walsh is uncredited for some of the direction, and I speculate the action scenes are those he worked on.
