Let's make this birthday one to remember.

85 years old (Born on June 18, 1939)

Happy Birthday, Jack O'Brien! Another year older and still directing circles around everyone else. From the vibrant hairspray clouds of Baltimore to the cheeky charm of The Full Monty, you've given audiences countless reasons to laugh, cheer—and occasionally blush. Your talent for turning musicals into award-winning masterpieces is legendary; clearly your secret ingredient must be a sprinkle of genius (or perhaps just really good coffee).

Here's wishing you another spectacular year filled with standing ovations and unforgettable curtain calls. May your birthday be as joyful as Tracy Turnblad's dance moves and as bold as those brave lads from Sheffield—though hopefully with fewer wardrobe malfunctions!
