Let's make this birthday one to remember.

48 years old (Born on April 29, 1977)

Happy Birthday, David Sullivan! From unraveling timelines in "Primer" to capturing audiences with performances that leave us scratching our heads—in the very best way—you've proven yourself as a timeless talent. Even now we're still untangling your memorable scenes and questioning: wait, was he already here?

Another year older means you're officially wiser at handling convoluted plots—but hopefully just enough birthday cake remains uncomplicated today. May your new age bring fewer paradoxes than Shane Carruth scripts and even more success ahead; after all, navigating life's timeline seems effortless for you!

Have an amazing day filled only with predictable fun surprises!
