Appreciating the trailer of the film, Bachchan offered his blessings and support for 'Heartless'.
"I am thankful to all for inviting me here and wish all the best to the team. Shekhar told me about this disease and we did whatever we could for him that time. For parents there is no big tragedy than losing your own kid when they (parents) are alive... At an early age," Bachchan told reporters here last evening.
'Heartless' is a romantic medical thriller based on the phenomenon of 'anaesthesia awareness'. Shekhar has dedicated the film to his elder son Aayush.
"I lost my son too early. He had a rare heart disease, I was not even aware of it. I was all alone in the film industry. I rang up Amitji first and he called me home and assured me he will help. He helped us a lot and I am grateful to him," he said.
