At age 63, actor Robin Williams' death has been a shocking tragedy for family, friends, and fans alike.

A close friend of the "Mrs. Doubtfire" actor has opened up to RadarOnline.com, saying that aside from his struggle with addiction, Williams recently spoke with a family friend of his "serious money troubles" and was troubled about his family's financial security.

As the family friend had claimed, "All he could talk about were serious money troubles. There were clearly other issues going on and Robin sounded distant during the telephone conversation."

The source also mentioned about how the Academy award winning actor was generous towards his family and friends with his successful movie career back in the day, and would "help anyone out that needed it."

It was also typical for Williams to be frustrated over having to take on roles for movies and television shows that he really did not want but needed to "for the paycheck". The source cited the actor's recent decision to push for "Mrs. Doubtfire 2".

"Doing sequels was never Robin's thing, and he wasn't that excited at having to reprise the role of Mrs. Doubtfire, which was scheduled to start filming later this year."

Williams has also filmed "Night at the Museum: Secret of the Tomb", the third movie in such franchise.

In an interview with Parade Magazine last year, the "Man of the Year" actor admitted that he agreed to star in CBS' "The Crazy Ones" because he needed the money.

 "The idea of having a steady job is appealing," the actor told the magazine. "There are bills to pay. My life has downsized, in a good way."

He also mentioned his ranch in Napa, the Villa Sorriso worth a whopping $35 million, and his decision to sell it because he could not afford it anymore.

While Williams had one of the most long-lived careers in Hollywood, divorcing from his previous wives- Valerie Velardi in 1988 and Marsha Garces in 2008- had such an adverse impact on his bank account.

The actor described divorce as "expensive" and compared it to ripping one's heart out through his wallet.

With "The Crazy Ones" being put to a stop, Williams went through a deep bout of depression and felt humiliated with the show becoming a failure.

According to the source, it had been an extremely difficult phase in the actor's life for him to accept.

"Here he was in his sixties, and forced to take a role on television for the money. It's just not where he thought he would be at this point in his life."

Williams left behind his third wife, Susan Schneider along with three children- 31-year-old Zachary Pym from first marriage to Velardi as well as 25-year-old daughter Zelda and 25-year-old son Cody, both from his second wife Garces.
