Of course a bad film affects all those concerned with the film. So everyone from Aditya to Shahrukh to Anoushka and Rahman will lose some sheen after the film settles down without impressing anyone and cheesing off so many more. The person who stands to lose most from the fiasco of JTHJ is Katrina, because it is her performance that has drawn the most flak.
Before this film, she was gaining some respect and acceptance as someone who was at last learning her acting chops. Films like Mere Brother Ki Dulhan, Rajneeti and Zindagi Na MIlegi Dobara were proof that she could pull off character driven roles and make female lead oriented films work. This one has revealed her to be what she was always thought off as – eye candy and a exciting dancer. What this will ensure is that she wont get too many plum roles.
The actress to gain the most out of the scenario is Deepika…not in small measure due to her performance in Cocktail – a film which has benefited all – Saif, Imtiaz, Diana, Pritam , and of course Deepika, because her performance was the highlight and surprised everyone with its quantum jump in quality.
She now has Kochadiyan with Rajni / Ravikumar, Chennai Express with Shahrukh/ Rohit Shetty, Race 2 with Saif / Abbas-Mustan, Yeh Jawani Hai Deewani with Ranbir / Ayan Mukherjee and Ram Leela with Ranveer / Sanjay Bhansali. DShe has it pretty much covered in terms of genres, co-stars and directors.
As I have mentioned bad film does not translate into bad box office right awy but affects the subsequent films of all involved. And it si the same with good films.
Mard may have done well in box office, but the audience dissatisfaction gets reflected after a time delay in subsequent films like Ganga Jamuna Saraswati and Jaadugar. On the other hand a god film like Jab We Met may not boast of great box office figures , but it leads to the good response of a Kaminay a Golmaal Returns or a Love Aaj Kal. Just like a Rockstar may not show up very well in box office terms but it primes the audience to come in drives for Barfi.
No body said cause and effect was simple. And least so in the slippery slopes of box office.
