he doctor is in. Seinfeld alum Jason Alexander has signed to star in a new comedy pilot for Adult Swim, created by Adam Lustick (The Harvard Sailing Team, Silicon Valley, The Office). The Untitled Jason Alexander pilot revolves around an award-winning psychotherapist (Alexander) who snaps one day and his therapy with his patients becomes more and more bizarre. However, he is such a celebrated doctor that his peers are reluctant to question his strange and unconventional methods. The quarter-hour, live-action pilot is being produced in-house via Alive and Kicking. Adult Swim is making its pitch to advertisers today during the Turner Broadcasting System upfront presentation in NYC. The Turner-owned net announced its 2015-16 slate last week ahead of today’s presentation.
