Mukul Dev started his acting career with the small screen where he did serials like 'Mumkin'directed by Mahesh Bhatt. Mahesh Bhatt again selected him for his film 'Dastak' with Miss Universe Sushmita Sen and Sharad Kapoor. Though he played the hard-core cop, nothing much happened and he remained stuck whenever he was. Many more of his films came and went without a whimper. There were some films like Umesh Mehra's Dilip Kumar and Rekha starrer 'Qila' and N Chandra's Nana Patekar and Madhuri Dixit film 'Wajood' which never saw the sparks of hope. He has been given ample of opportunities but has not able to utilise them properly. There was his 'Mere Do Anmol Ratan' with Arshad Warsi and newcomer Namrata Shirodkar which bombed miserably. Then another of his film 'Iski Topi Uske Sar' joined the list of his flops. like Amitabh Bachchan starrer 'Kohram', Vivek Vaswani's 'Sar Ankhon Par', 'Jai Surya', 'Ganga Jamuna', 'Dada Thakur' and 'Hum Tum Aur Who'. One movie which still needs to be sold is ABCL's 'Naam Kya Hai'. The film is long being complete but is on the look out of a buyer who can help show it the day.
