"He's a good man, he's an incredible person, I love him and I can't imagine what he's been going through," Anderson said, who visited Assange several times during his near seven-year stint inside the embassy, creating speculation about their relationship.
On Tuesday, Anderson was accompanied by WikiLeaks Editor-in-Chief Kristinn Hrafnsson, who said the duo were "quite emotional" following the visit. The 47-year-old has been forced to spend 23 hours a day in his cell, he added.
"It is for me shocking to see my friend, an intellectual, a publisher, a journalist. A man who has transformed the world of journalism with his work sitting in a high-security prison," Hrafnsson said.
"Someone said that you could judge the civilization of a society by visiting its prisons and frankly I have to say from my heart that this visit did not reflect well on this society here."
Assange's stay in the embassy was brought to a dramatic close on April 11 when Ecuador withdrew his asylum and invited in British police, citing his bad behaviour. He was then forcibly removed by officers.
The Australian was handed a jail term of almost a year on May 1 for skipping bail in 2012 when he sought political asylum in the embassy.
Assange was wanted in Sweden for questioning over sexual assault and rape allegations, The whistleblower has repeatedly denied any wrongdoing and said he sought refuge in the embassy over fears of being extradited on from Sweden to the US due to his work with WikiLeaks.
He is battling against extradition to the US on a computer hacking conspiracy charge, in which proceedings have been adjourned until May 30.
Belmarsh prison in Thamesmead, southeast London, where Assange is being held, is known to have housed some of Britain's most notorious terror suspects including Abu Hamza al-Masri and Anjem Choudary. It has the capacity to hold more than 900 inmates.
Hrafnsson said Assange was "bent but not broken" following the arrest and that "his spirit is strong."
"He is an extremely resilient person and I want you to think about the fact that such resilience usually comes from the fact that he knows that he is innocent," he said.
