For reasons unknown I did not see Saturday Night Fever upon its first release in December of 1977. However, I made up for that missed opportunity in early 1993 when the fabulous Bloor Cinema here in Toronto fulfilled its role as a top repertory movie house. In 1992 alone I saw about 150 movies there. What was playing was not an issue at all to this movie fan: I would pop out of the subway -- "Bathurst" station -- on my way home from work and pop into the royal movie place. (Once I double-dipped without realizing it. "I've seen this; when it came out.")
I was glad to finally get around to seeing the Fever. Much of the audience had seen it, that much was clear to me. They howled during the opening credits sequence, specifically the very low shot of John Travolta's boots Ping-Ponging to and from the camera lens. I too laughed. Awesome filmmaking. Later, when the star applied the essential 1970s hair blowdryer, the audience went nuts.
I loved the film, as a film. It deserves its "classic" status. The dance scenes are almost transcendental.
Last night I watched it again, this time on DVD. Absolutely a wonderful and joyous piece of movie entertainment; even with the non-PG moments.
