What is Wayne Knight doing now?
Wayne Knight is still very much in the game. In 2025, he appeared in the horror sequel Five Nights at Freddy’s 2 as Mr. Berg (TV Insider (entertainment guide)) and voiced characters in Among Us and Goat (IMDb (filmography database)). He also showed up in TV dramas like 9-1-1: Lone Star and the comedy Bookie.
What projects is Wayne Knight currently working on?
He is listed for St. Denis Medical in 2026 as Dr. Felix Axler (Wikipedia). A voice role in Goat (2026) is also confirmed via BroadwayWorld credits (BroadwayWorld (theatre and performance database)). His schedule suggests a healthy mix of voice work and live-action parts.
Is Wayne Knight still acting in 2025?
Yes. Besides the film roles mentioned, he remains a working actor. According to IMDb (filmography database), his filmography includes a steady trickle of new credits each year. No retirement plans have been reported.
Does Wayne Knight have a social media presence?
He is active on X (formerly Twitter) under the handle @iWayneKnight, where he posts about his projects, shares observations, and engages with fans. It’s one of the few direct ways to hear from him.
The implication: a steady stream of varied roles keeps Knight relevant in a shifting industry.
How did Wayne Knight lose so much weight?
Knight lost roughly 110 pounds over several years. The motivation came from a doctor’s grim warning: he was approaching morbid obesity and at risk of diabetes (IMDb (Spanish page biography)). He changed his diet and started walking. The process was gradual—not a quick fix.
Did Wayne Knight use Ozempic for weight loss?
Multiple reports quote Knight directly denying the use of Ozempic. In a RadarOnline (celebrity news site) interview, he credited diet and exercise alone. The narrative of a “miracle drug” does not fit his timeline or his own statements.
How much weight did Wayne Knight lose?
He has said he lost about 110 pounds since his Jurassic Park days (Yahoo Entertainment (news outlet)). Some sources, like the IMDb Spanish page, give a slightly different number (117 pounds, from 327 to 210). The difference is minor; the consensus is a dramatic drop of more than 100 pounds.
What motivated Wayne Knight to lose weight?
He reported that a scene from Seinfeld where his character runs caused him heart palpitations. A doctor told him he was headed for diabetes (IMDb (Spanish page biography)). That scare was the turning point. By his own account, the weight loss came from sustained walking and better eating habits, not surgery or medication.
The Ozempic rumor is a symptom of our shortcut culture. Knight’s story shows that slow, consistent change—not a drug—can produce huge results. For anyone looking to lose significant weight, the takeaway is patience and a daily walking habit, not a prescription.
The trade-off: Knight has said his weight loss cost him some acting roles because he no longer fit the “funny fat guy” mold (Yahoo Entertainment (news outlet)). The industry typecast him, and after the transformation, casting directors didn’t know where to place him.
Did Jerry Seinfeld like Wayne Knight?
Yes, and the evidence is on record. Jerry Seinfeld spoke positively about Knight’s performance as Newman, acknowledging that he was the perfect foil for his own character. In interviews, Seinfeld praised Knight’s comedic timing and professionalism. No public feud exists.

Account from cast and crew indicate a friendly, professional relationship. There is no credible report of conflict. The “did they hate each other?” question is a fan myth, not a real rift.

The pattern: on-screen friction often masks real-world respect.

Is Wayne Knight better known for Seinfeld or Jurassic Park?
