 In Tony (John Travolta (qv))s bedroom, we see a poster for  _Rocky (1976)_ (qv), a film directed by John G. Avildsen (qv). The  sequel to Saturday Night Fever, _Staying Alive (1983)_ (qv), is  written and directed by the star of Rocky,  Sylvester Stallone (qv). In fact, Avildsen was the original  director of "Fever" but he left the project shortly before principle  photography began over creative differences. John Badham (qv) was  approached to fill in at the last minute.
