These A-list actors started in horror movies, sometimes very low budget, but went on to mainstream success.
Jamie Lee Curtis is a prime example, starring as Laurie Strode in the original 1978 Halloween and reprising the role in many sequels, including the recent reboot trilogy.
She even made two small cameos in Halloween 3: The Season of the Witch, which departed dramatically from the Michael Myers storyline.
Curtis also appeared in hits like Trading Places, A Fish Called Wanda, and True Lies, before winning an Oscar for Everything Everywhere All at Once. She appeared in Halloween Ends, showing her ongoing connection to horror movies.
