Let's make this birthday one to remember.

54 years old (Born on December 29, 1970)

Happy Birthday to the legendary Kevin Weisman! From your unforgettable turn as Marshall Flinkman on "Alias"—where you proved geeks could indeed save the world—to your most recent captivating appearances in projects like "Runaways," you're still stealing hearts (and scenes!) everywhere.

Whether hacking into clandestine networks or just effortlessly delivering a clever one-liner, you've given fans countless memorable moments and reasons for laughter. May this year bring even more mischief, joyful adventures, and hilarious dialogue worthy of repeat quotability—but preferably fewer evil villains chasing after you!

Here's wishing Hollywood's favorite tech genius another fantastic trip around the sun!
