Williams' passing came as a shock to fans, his publicist noted in a statement that "He has been battling severe depression of late." He also notably struggled with drug and alcohol abuse throughout his career, having checked into rehab in early 2014.

Even President Obama expressed his condolences. "He arrived in our lives as an alien -- but he ended up touching every element of the human spirit. He made us laugh. He made us cry," Obama said in astatement. "He gave his immeasurable talent freely and generously to those who needed it most -- from our troops stationed abroad to the marginalized on our own streets."
