Mini-rant

Films aren't "based off of" books, they're "based on" books. A house isn't "built off of" a plot of land, it's "built on" land. The first way sounds idiotic and illiterate.

Books aren't "released," they're published. Films are "released." (Except for the ones that escape by themselves.)

Plays aren't "shown" (as in "Fences is showing at the Cort Theatre" they are produced or presented. Movies, paintings and houses are shown.

If everything is going to be the same as everything else, why have different words at all? Why not just have one word that means everything?

As you were.
