Let's make this birthday one to remember.

75 years old (Born on March 18, 1950)

Happy Birthday, Brad Dourif! From your unforgettable portrayal of Billy Bibbit in "One Flew Over the Cuckoo's Nest," you've shown us that sometimes it's okay to be a little cuckoo. Your brilliant performance taught us all how laughter and tears can coexist—usually at Nurse Ratched’s expense.

Whether you're voicing Chucky or bringing depth to complex characters on screen, you continue proving age is just another number (though hopefully less scary than one of Chucky's sequels). Here's wishing you a birthday filled with fewer creepy dolls and more cake slices—and may no nurse interrupt your celebration this time around!
