Okay, pop quiz:

Which of these classic movies, each perfect in its own way, is currently undergoing a completely unnecessary remake, “re-imagining,” or revisiting of the original story in order to “update” the film for modern audiences?

A. “The Wizard of Oz”
B. “Poltergeist”
C. “The Untouchables”
D. “Se7en”

The answer?

Actually, it’s a trick question: remakes are currently in the works for both “The Wizard of Oz” and “Poltergeist,” while “The Untouchables” and “Se7en” are being subjected to ill-advised prequel treatments. Hollywood is officially out of ideas.
