Now that Clint Eastwood has broken my heart by dismissing his return as Dirty Harry, I must turn my fetish for senior citizens with guns toward this week's DVD releases. The writer of 1976's Best Picture winner shows off his penchant for steroids and graphic violence in the Rambo DVD box set. The set includes First Blood, Rambo: First Blood Part II, Rambo III and just plain old Rambo. Harrison Ford may have taken 19 years to put his fedora back on, but Sly has him beat: It took Rambo 20 years to tie on his headband and rediscover his taste for a little of the old ultraviolence. I bet the box set has one of those old McDonalds sign counters: "Over One Billion Killed!"
