Literary reference

I have searched and searched online for a definition of "literary reference." My question is, can the term be stretched to include not just works of literature but plays, movies, etc.

I was talking about a reference to a movie and used "literary reference." I was corrected (I hate that) and told what I mean "cinematic reference."

I backpedaled/saved face by saying the work in question was literature (a book) before it was a movie. But I am still curious about whether the term can be stretched a bit.

I hate being wrong.

Me too. Having looked at a dictionary entry for "literary," I think the word would break if stretched as far as movies.

Dang.
