Semi autobiographical of Stallone's poor days as a struggling writer/actor in New York, Travolta is seen showering with clothes on as Stallone did when he couldn't afford to wash them at a launderette.
John Travolta wasn't the only one puzzled by Sly's idea for "Satan's Alley". On VH1's "I Love The 80s Strikes Back", Sly's brother Frank Stallone recalled seeing copies of books with devils in them and "wondered what it had to do with 'Saturday Night Fever'". Finola Hughes was confused as well and she "was in it for six weeks!".
