New Delhi - India's entertainment capital of Mumbai is in a state of shock due to the terrorist attacks across the city, with reports of at least one Bollywood superstar sleeping with a gun under his pillow.

Mumbai is home to the Hindi film industry, popularly known as Bollywood.

Iconic star Amitabh Bachchan, who has played the role of superhero in several Hindi movies, described it as a "terrible situation" that disturbed him.

"As the events of the terrorist attack unfolded in front of me, I did something for the first time and one that I had hoped never ever to be in a situation to do," Bachchan an icon of the Hindi cinema wrote on his blog.

"Before retiring for the night, I pulled out my licensed .32 revolver, loaded it and put it under my pillow, for a very disturbed sleep," he said.

Bachchan said he was glued to the TV screen late on Wednesday night when security personnel battled the terrorists who killed 125 people across the city formerly known as Bombay.

Many Bollywood stars were angry with the inability of the government to deal with terrorism. India has seen a number of bombings over 2008, with attacks occurring almost every month.

"It's time for the corrupt politicians to wake up. Stop thinking of your vote banks and think of what's happening to the country," Raveena Tandon, a Bollywood actress, told the IANS news agency.
