The (quasi) subject of a recent thread, "Cool As Ice:"
"When a girl has a heart of stone, there's only one way to melt it. Just add Ice."
Considering that the girl in question really didn't have a heart of stone. Well, I guess that's the film's least problem.
Screamers:"They're men turned inside out! And worse...they're still alive!"
I guess, after consideration, that I went for taglines that really didn't fit the movie they described.
