Henry Winkler calls 'Happy Days' co-star Ron Howard "limitless" after his Emmy nomination for 'The Studio'

Ron Howard earned his first-ever acting Emmy nomination for his guest role in Apple TV+'s 'The Studio,' which garnered a total of 23 Emmy nominations. Naturally, his former 'Happy Days' co-star and longtime friend Henry Winkler was quick to share his pride in the accomplishment.

"I called him immediately. He was so excited," he told PEOPLE. "He is limitless." The two even spoke before Howard filmed his scenes. "He loved it," the actor revealed. "He said to me, 'I'm doing it and I'm going full-tilt.'"

In “The Studio,” Seth Rogen stars as Matt Remick, the newly appointed head of embattled Continental Studios. As movies struggle to stay alive and relevant, Matt and his core team of infighting executives battle their insecurities as they wrangle narcissistic artists and craven corporate overlords in the ever-elusive pursuit of making great films. With their power suits masking their never-ending sense of panic, every party, set visit, casting decision, marketing meeting and award show presents them with an opportunity for glittering success or career-ending catastrophe. As someone who eats, sleeps and breathes movies, it’s the job Matt’s been pursuing his whole life, and it may very well destroy him.

The Studio has had some incredible guest stars in the first season alone, whether they played a character or an over-the-top version of themselves. So could we ever see Winkler joining the cast for some laughs?
