He was also good friends with comedian John Belushi, who died of a drug overdose in 1982. In fact, De Niro and Robin Williams were the last stars to see Belushi alive, albeit on separate visits to L.A.’s Chateau Marmont hotel that sad day. De Niro visited Belushi at 3:00am on the morning of his death, but, according to eyewitnesses, left minutes later after seeing that Belushi was ill. Less than an hour earlier, Belushi had been visited by Robin Williams.
