Britain's Guardian newspaper has posted the deleted scene on its website and has proposed that it be restored to the recently released DVD version.
The newspaper has, however, refused to disclose how it received the clip.
"We find ourselves looking on it as a missing piece of the jigsaw, if not a tantalizing glimpse of the Film That Might Have Been," Contact music quoted Guardian film critic and media writer Xan Brooks as saying.
Brooks says that scene provides a glimpse of the character's humdrum existence at the time.
"I think Slumdog Millionaire would have been a marginally (stress marginally) better film had it been included," Brooks added.
