Robin Williams rejected a $600,000 offer to headline two Las Vegas shows two years before his death.

The 'Mrs Doubtfire' actor, was found hanged at his home on August 11, turned down the chance to headline two shows at The Colosseum at Caesars Palace in Sin City, according to an AEG Live document obtained by TMZ.

The late actor was shooting CBS sitcom 'The Crazy Ones' - which lasted for just one season - at the time he declined the offer and it appears to further quash rumours that he had financial problems at the time of his tragic death.

Robin's publicist Mara Buxbaum has also insisted the 'Dead Poets Society' star did not have money troubles before he died and instead believes ''severe depression'' led to his suicide.

She recently said: ''Robin had no financial problems. We should be blessed to have Robin's financial status. I understand the desire to understand the 'Why.' It's not going to happen.

''The better thing to do is to try to understand severe depression. That isn't going to be answered, and you can speculate all you want.''

Shortly after his death Robin's third wife Susan Schneider revealed he had recently been diagnosed with Parkinson's Disease.
