Muhammad Ali net worth - The total earnings of this legendary boxer has been on the minds of many fans following the release of a documentary about his life over the weekend.

The documentary, 'I am Ali', presents a well preserved window into the life of one of the most controversial competitors in the history of boxing and sports in general.  

Hana, one of his daughters, has revealed that "He's always defied impossible odds, doing the seemingly impossible and I want people to take away the incredible human being that he was, the love that he had for his children and people and his incredible spirit."

Mohammad Ali's net worth is estimated to be about $50 currently. This is about $30 million less than it was two years ago.

The 72-years-old was diagnosed with Parkinson's disease in the 80s and this condition has greatly affected his life. Reports indicate that he is increasingly frail and does not "speak too well."

His brother Rahman Ali, who was constantly by his side throughout his storied career, has revealed that he couldn't talk to his brother about the recently released movie on his life because he is sick. Nonetheless, he expressed confidence that the highly ranked boxer "has given this film his blessings."

Pundits say Muhammad Ali's net worth has been seriously affected by the fact that he is unable to work actively to make more money. Also, his treatment is believed to have put a strain on his finances.

Muhammad Ali's net worth shot through the roof after he took on Sonny Liston for the world heavyweight title in 1963. His witty distractive antics quickly won him the admiration of many. In the 60s, Muhammad Ali controversially refused to fight in the Vietnam War. As a result he was stripped of his title and had his boxing license revoked. But Muhammad Ali cleverly won the public's support on the issue and got his license reactivated; winning the historic match against Joe Frazier to reclaim the heavyweight title and cement his place as one of the most memorable athletes of all times.
