Don't be afraid of the dark

Office obsession of the week: The M&M dark chocolate game. The link started making the rounds last Friday and was still getting a fair amount of attention today. It's fun. The object is to name the 50 'dark' movies represented within the imagery.
Several movies are represented in the snap above including: House of Wax, The Village, Signs and Pumpkinhead. Several have been challenging for me and most are fun or interesting when discovered. Only one (so far) stretches beyond challenging to stupid (Rear Window).
As of tonight I've discovered 44 out of the 50. I've probably given it 60-90 minutes between yesterday and today. No cheating yet but Six did give me a hint on the pennies ("count them").
I'm stuck on the wooden-headed thing, the bug in a jar and the planets. Maybe I'll have more luck thinking about them offline.
BTW, I hate dark chocolate.
