The prospect of returning to series television was intimidating at first, Robin Williams said Wednesday night at TCA. The star of CBS’ The Crazy Ones said the worst part was “the pressure of it being A Robin Williams Vehicle”. Now the series is more of an ensemble, and “that’s the great joy for me – the pressure is off. It’s really become something I enjoy,” he said, adding that he no longer is nagged by the pressure of ” ‘You’re back on TV. After 32 years.’ The ensemble is so good, and we’re growing,” he said, speaking glowingly of the “steady gig like this with a great group of people.”

Williams headlines the David E. Kelley comedy as Simon Roberts, head of a Chicago ad agency, whose daughter, played by Sarah Michelle Gellar, is a business partner. Cast member, Hamish Linklater said the two of them assume most of the load on the show, calling Williams an “amazing captain.” Williams began captain-riffing.

“Like helium – our helium captain,” Linklater cued Williams.

Williams introduced Captain On Helium.

“Our Irish helium captain!” barked Linklater.

“Oh, Danny Boy, the pipes, the pipes are calling,” Williams began to sing, like an Irish captain, on helium.
