Then came Jai Kishen(1994) starring Akshay Kumar in a double role and Ayesha Julka. The film was a Semi Hit at the box office. Sunil Agnihotri's first work for TV was the biggest success in 1994/95 with a fantasy series called 'Chandrakanta partly based on Devaki Nandan Khatri's novel Chandrakanta. The series became so successful because of its grand making and introduction of special fx that the entire India was at standstill from morning 9 to 10 a.m. on Sundays.Many actors from this series became very popular like Irrfan Khan, Rajendra Gupta, Kruttika Desai. Then his series Yug, which ran from 1996 to 1998, tells the story of a freedom fighters struggling for freedom with the British, in the days of the British Raj.

He then went on to produce and direct in 1997 a series called Betaal Pachisi which was a very successful as a TV fantasy series. However that year, he faced a lawsuit involving the US. King Features Syndicate filed a case arguing that Agnihotri had copied the idea of The Phantom comic strips for the Betaal series.

After Betaal Pachisi Sunil Agnihotri went on to direct series like Satyawadi Raja HarishChandra, Gulsanober and so on.
