Mumbai, April 21 (IANS): Megastar Amitabh Bachchan, whose memorable film "Don" completed 37 years of its release on Tuesday, is glad that the "incredible" journey of the film "still continues"

The movie is an action-thriller, which revolves around a powerful gangster named Don played by Amitabh, who was seen in a double role in the film.

"37 years of 'DON’ today (Tuesday). A film made by that gentle giant Nariman Irani, the DOP of extreme excellence,” Big B wrote on his blog.

The 72-year-old is ecstatic about the film's journey and he even took to his micro-blogging website Twitter to express his happiness with his fans and well-wishers.

"37 years of DON .. today!! Incredible! A journey that still continues," he tweeted.

The actor also shared anecdotes from the set of the film -- especially one when producer Nariman A. Irani saved a child at the Rajkamal Studios, while he was shooting for a film there.

"Ran (Irani) to save the child. He did. But injured himself in the effort. Broke his femur, was hospitalised, went into surgery and came out well. Few days later complications set in and he passed away," Big B wrote.

Also reminiscing the iconic song "Khaike paan Benares waala", he said it was shot in second shifts at Mehboob Studios from 2 to 10 p.m.

"During the action scene, I had hurt my feet and had huge burn boils on the palm of my feet. Could not wear shoes, or walk. The song was bare foot...so...took pain killer injections on my feet before each shot and completed the song and the scene," Big B wrote on his blog.

The actor was congratulated for the song by then writer duo Salim Khan and Javed Akhtar. The duo saw the rushes of the film and sent a telegram to Srinagar where the megastar was shooting.

"Salim-Javed saw the rushes of the film... more importantly, the rushes of the paan eating duplicate DON, and sent me a telegram, in Srinagar where I was shooting for another film congratulating me," Amitabh wrote.

"It was a most encouraging moment for me I remember. I still remember the room in the Palace Hotel, when I received the message, and my inner feeling of great joy on its contents," he added.

A remake and sequel of the film were released in October 2006 and December 2011, respectively which starred Bollywood superstar Shah Rukh Khan.

Directed by Chandra Barot, "Don" is considered to be one of the most iconic movies of Bollywood.

The megastar was last seen in "Shamitabh" and will soon be seen in Shoojit Sircar's "Piku" and Bejoy Nambiar's "Wazir".
