Let's make this birthday one to remember.

78 years old (Born on July 20, 1946)

Happy Birthday, Randal Kleiser! From making us groove with "Grease," to whisking us away on a tropical adventure in "The Blue Lagoon," you've always known how to keep audiences entertained. And let's not forget the hilariously oversized antics of "Honey, I Blew Up the Kid"—you truly have a knack for turning everyday chaos into cinematic gold.

May your birthday be filled with more laughs than Danny Zuko's dance moves and adventures as memorable as Brooke Shields stranded on an island. Here's hoping this year brings you even bigger successes—but maybe avoid blowing up any kids this time around!
