Questions that pertain to a bunch of a different media (TV, Movies, Music) may have a place in Entertainment. I'm not sure what kind of brain teaser you were aiming for, but Entertainment has a Word Play category. Alternatively, if it's just themed around a certain subject/word, it might go in Entertainment Mixture or Grab Bag somewhere.
I'd suggest sending a note to kyleisalive, and he can tell you if your quiz can find a home in Entertainment.
