Crank fared relatively well at the box office and was an entertaining movie for what it was. It makes sense they’d do a Crank 2 despite what happened at the end of the first. It also makes sense that they’d film Amy Smart with black tape over her nipples. Something that doesn’t make sense though? Platypuses. Baby platypuses lick milk secreted from glands instead of nipples on the side of their mother’s body. What gives?
