Bollywood is getting fond of supernatural things and special effects, day by day. While Sanjay Dutt is playing Yamraj in 'Wah…Life Ho To Aisi', Sharmila Tagore is playing a ghost in Aparna Sen's next release. Hrithik Roshan is ready to do superhero act in 'Krrish' and Rekha is too playing a fictitious character (in a novel), who suddenly comes alive and converses with the author.
