Those already captivated by Charles Barkley’s arrogant, attention-grabbing antics as the NBA’s most colorful star will naturally clamor for Sir Charles. What’s surprising is that you don’t need to be a Barkley addict to fall under its spell. Narrated by Avery Brooks (Deep Space Nine), this bio reveals Barkley’s unlikely past. An overweight, insecure kid who grew up poor in Leeds, Ala., Barkley — the pride of the Phoenix Suns and last year’s MVP — didn’t exhibit his astonishing power-forward talents until his late teens. Though there’s a little too much footage of the 1992-1993 playoffs, Sir Charles is almost as much fun to watch as Sir Charles is.
