Tanveer, Karishma, Urmila, Akhtar Khan, Firoz Khan, and Junior Amitabh Bachchan
The narrative revolves around the lives of four bachelors who arrive in Mumbai with dreams of making it big. Like many newcomers to the city, their first hurdle is finding a place to live. The title 18 Kunwara Paying Guest refers to their status as "kunwara" (unmarried/bachelor) tenants, a demographic often viewed with suspicion or reluctance by landlords in Indian society.
Maybe the film is listed on IMDb under a different title. I should search for "Kunwara Paying Guest 2007" on IMDb. search result 0 might be a placeholder page. It says "Kunwara Paying Guest - Showtimes & tickets". But there are no showtimes. It might be that the film is not listed in IMDb's database.
