Henry Winkler

Ain't this cool? Former Fonz, Henry Winkler, is being eyed for the role of Ava's father, Robert, on NBC's Up All Night. "We're excited about Henry Winkler, and Maya Rudolph [Ava] just adores him," says the show's executive producer, Emily Spivey.

While Ava's mama was nutso, Spivey says Robert is "the more grounded and warm, loving parent. Even though he's flighty and a little irresponsible, he's a creative type who writes children's books. Henry, in the roles he's played, exudes a warmth and whimsy, which is why we thought of him."

In real life, Henry has authored the successful Hank Zipzer series of children's books, which was news to Spivey. "No way! I had absolutely no idea," she said when I clued her in. "I can't wait to talk to Henry."

Look for the character to debut in late April/early May, while Ava's mother, who tends bar in Florida and lives with a musician, would debut in Season 2.
