“Frozen” and “Fifty Shades Of Grey” are the two films that the Internet can’t seem to stop buzzing about, but they’re also two films that couldn’t be further apart.

In theory.

There are similarities, to be sure, between “Frozen” and “Fifty Shades Of Grey.” Both feature young women meeting a sophisticated man who they — maybe too quickly — fall for. Plus, Both Prince Hans and Christian Grey have desires that lie outside the conventional romantic relationship.

But while Prince Hans locks his “beloved” up because he wants her sister’s throne, Christian Grey has a dungeon for … other reasons. Reasons that could make a Disney princess blush.

“Fifty Shades Of Frozen” fits together just a little too well for our comfort, but like the movies that inspired it, it’s a must-see.
