AMC presents a double feature of movies featuring Clint Eastwood’s iconic “Dirty Harry” Callahan. First up: This 1971 titular showcase, followed at 8:15 p.m. ET by 1973’s Magnum Force. Eastwood fans should feel very fortunate, considering what a slow TV night this is. So the question is: Are you an Eastwood fan, and do you feel fortunate? Or, to put it Harry’s way: Do you feel lucky, punk? Well, do you?
