Robin Williams dead at 63: ‘Mork & Mindy’ co-star remembers the late comedian as a sad, solitary man Jay Thomas, who co-starred on ‘Mork & Mindy’ with Williams, said the legendary funnyman always kept others at bay. ‘I don’t know that anyone knew Robin,’ Thomas said. BY BRIAN NIEMIETZ NEW YORK DAILY NEWS Tuesday, August 12, 2014, 9:38 PM Jay Thomas co-starred with Robin Williams on 'Mork & Mindy” from 1979 to 1981. Robin Williams was a solitary man who struggled to find the happiness he so easily brought to others. That’s how his "Mork & Mindy" co-star Jay Thomas remembered him Tuesday, one day after the legendary funnyman hanged himself in his northern California home after a struggle with depression. "I don't know that anyone knew Robin," said Thomas, who played deli owner Remo DaVinci on the ABC hit show from 1979 to 1981. "He kept you at bay. I don't think I would've known Robin any better if we'd been pals for 30 years, than I did in the three years I spent with him." The duo certainly partied hard in those days, but for the New Orleans-native Thomas, the boozing and carousing was all in good fun. For Williams, something sad was always lurking. "One time, we were all drunk up, and he said, 'I'm jealous of you,'" Thomas recalled. "He meant that he was jealous of the fact that I enjoyed” the fame and carefree fun. It was the one time Thomas felt he had entered Williams’ fortress of solitude. But it was short-lived. “The next day at work, it was as if we'd never spoke and he wasn't friendly,” Thomas recalled. “I thought we’d had a breakthrough. "We always had fun together, but (we) would all be going out somewhere to eat ... and Robin would be gone.,” Thomas said. “He'd always disappear.” Thomas linked Williams’ longtime struggle with depression to his childhood as a chunky lonely kid. 'I don't know that anyone knew Robin,' said Jay Thomas, who played deli owner Remo DaVinci on 'Mork & Mindy.' "He once told me he stayed in his room a lot," Thomas said. "Just because you become a superstar doesn't mean that you forget being picked on as a kid." As a result, Williams could “never really relax” on stage or off, according to Thomas. "This is a guy who battled demons,” he said. “He could sit and talk about stuff, but you didn't have a long conversation with Robin, ever. He didn't sit at a table (with cast members), talking about something. He'd get up and he'd be gone and you'd have to realize that's who he was.” Thomas last saw Williams a decade ago when they ran into each other on vacation in Jamaica. The pair shared a few laughs, but Williams disappeared back into his own world. "You could see all of this stuff coming," Thomas said. But even if he could see impending doom on the horizon, Thomas was surprised by the violence that Williams — “a peace and love guy” — exhibited in his suicide. "At the end of his life, he did something violent,” Thomas said. “He didn't take a pill. He didn't get in the car (and turn on the ignition). The fact that he did something violent and rash makes me think, that was torture. Robin must've been going through some really dark things." Thomas blamed the comic’s handlers for not doing more to ensure his safety. “With the insulation that a star has, no one is going to tell their multi-million-dollar meal ticket, 'You need to get some help.'"
