I agree, Jia Khan had a unique dusky beauty and a strong screen presence, she was very charming on screen and in Nishabd she was really good as a first timer performer in an unconventional role.
Even I wonder why she didn't got more chances after her debut. as a lead, I guess it is due to her first film flopping, was a very controversial one and she never had that strong internal network in the industry unlike Deepika who was a famous model already and had connections within, but the main thing was her debut becoming a blockbuster.
Even if OSO would have flopped it would have been hard for Deepika as well to survive just like what did happened with Gyatri Joshi in Swades despite having a beautiful face and performed brilliantly.
Deepika not just was dubbed but mostly she done nothing but burst bubble gum balloons in OSO, what went to her advantage was her sex appeal and her looks and makeover as a yesteryear's heroine which fitted like T on her persona, Deepika is a one lucky girl, and in the industry much more then talent or performances it is mainly the luck which stands out as the biggest factor to make or break anyone, as everyone do real hardwork but mainly luck decides who stands where, even the boxoffice results are mostly luck driven as many trashy films got hit and genuinely good films get flopped.
