Saif Ali Khan as the terrorist who manipulates Kareena Kapoor into marrying him so that he can legally enter the US to carry out the planned terrorist attacks masterminded by Om Puri is simply brilliant in this movie. Initially, he comes across as a genuine and charming young man Ehsaan Khan trying to woo the beautiful Avantika Ahuja (Kareena Kapoor) and even convinces her father into agreeing to let her marry him. Then he systematically and cleverly manipulates Kareena into wanting to live in a predominantly muslim neighborhood which actually is inhabited by his fellow terrorists. Kareena Kapoor as the trapped and cheated wife also gives a convincing performance. Vivek Oberoi is good at times. Kiron Kher as Om Puri's wife also delivers a compelling performance.
