Let's make this birthday one to remember.

60 years old (Born on April 17, 1965)

Happy Birthday, William Mapother! May your day be filled with fewer mysterious islands and more cake-filled adventures. Your unforgettable portrayal of Ethan Rom on "Lost" still gives us chills—and makes us suspicious every time we meet someone named Ethan.

From navigating eerie jungles to keeping audiences guessing episode after episode, you've mastered the art of suspenseful storytelling. Here's hoping this year brings you roles as intriguing (but perhaps less sinister) than your iconic character. Enjoy celebrating another trip around the sun—just remember, if anyone offers you a flight over an island today, maybe politely decline!
