The cast of Gurudev in the posters and postcards that were released prior to the film's release in 1993. As you can see from the publicity stills, though Rishi and Anil Kapoor were the 'heroes' of the film, both fine actors were second to the diva of the decade, Sridevi.
She was used in multiple stills throughout the shots as she had the fun double-role. Having starred in multiple films as a double act (be it Chaalbaaz, Lamhe, Khuda Gawah, Nigahein... so on and so forth - not to mention her South Indian films where she essayed more than one role!), Sridevi probably holds the record as India's most versatile actress.
