Let's make this birthday one to remember.

74 years old (Born on February 16, 1951)

Happy birthday, William Katt! Who knew you could survive crash-landing through every rooftop in Los Angeles and still look this good? We're celebrating the guy who wore red tights with grace (well...sort of), reminding us that heroes don't need smooth landings—just good hair and pure determination. "The Greatest American Hero" itself proved there's nothing funnier or more humanizing than a superhero fumbling to master his powers.

And let's not forget your remarkable roles beyond superheroes: you've soared on Broadway stages, conquered memorable movies like "Carrie," and continue thrilling devoted fans at conventions everywhere. Keep flying fearlessly—birthday suit optional!
