I heard about these a few days ago and thought they were Youtube fan flicks. But, no, they’re the real deal: Along with the Season 4 DVD comes a handful of exclusive Wire prequels at Amazon.com, including looks at young Omar and Prop Joe in action and Bunk and McNulty’s first bender. Season 5: January 6, or Dec. 31 if you’re On Demand-inclined. (Teasing press-release summaries here.)
