During the shoot of a sequence for Wake Up Sid, Konkona Sen Sharma had a horrifying experience. The actress, who has a fear of mice, had to shoot with a real one on the insistence of director Ayaan Mukherjee.

At first when Ayaan mentioned shooting the scene, which would involve a rat crawling over her body, she thought they would either use a fake rat or her dummy.

But they brought in a real mouse, colored it black with shoe polish and set it on her. She covered herself with two quilts and hurriedly shot for the scene while being frightened to death.

She feels that's one experience she will never forget and never wants to repeat it ever again.
