The Rocky Horror Picture Show (1975)

I don't know exactly how I discovered The Rocky Horror Picture Show as cult movies weren't something I'd watch. I just know that, when I first watched it, many years ago (I believe I still was in my teens), I was not ready for it but I loved it nevertheless. Since I'm doing this Horror October thing, I figured it was time to rewatch it. 

The film follows Brad (Barry Bostwick) and Janet (Susan Sarandon), a newly engaged couple whose car broke down in the middle of nowhere during a rainstorm, and, while seeking a telephone, stumbled upon the castle of Dr. Frank-N-Furter (Tim Curry), a transvestite from transsexual Transylvania. From then on, a series of weird and bizarre things begins to happen.
