Let's make this birthday one to remember.

47 years old (Born on October 19, 1977)

Happy Birthday, Jason Reitman! From "Thank You for Smoking" to your brilliant storytelling in films like "Juno," you've proven that sharp wit and clever dialogue run deep—clearly inherited from the legendary Ivan. Your talent behind the camera has given us countless laughs, thoughtful moments, and unforgettable characters.

As you celebrate another year of cinematic genius (and perhaps a few more gray hairs), remember: age is just a number—but comedic timing? That's timeless. Here's hoping this birthday brings as much joy as your movies have brought audiences worldwide. Cheers to many more years of laughter, creativity, and success!
