Repackaged amaray. From the fine 1922 silent Robin Hood with Douglas Fairbanks to the Kevin Costner vehicle Robin Hood: Prince of Thieves, Sherwood Forest has been fertile ground for moviemaking. No version, though, says "Welcome to Sherwood," with anywhere near the pizzazz of this 1938 classic, in which Errol Flynn memorably utters that very line from atop a tree limb, smiling with the debonair grace that defined his legend. The story's framework is adventure 101: Robin takes on the bad guys in the name of justice and, after a few setbacks, emerges thrillingly victorious in a climactic showdown and wins the hand of Maid Marian.
