Sonam, who plays slain stewardess Neerja Bhanot in the film, asked fans and followers to post video messages about their biggest fear. "What, me fear?" was Shahid's response.
That is, until wife Mira peeked into the frame.
Messages also came in from Sonam's father Anil Kapoor, her Dolly Ki Doli producer Arbaaz Khan and director Homi Adajania.
