John Travolta
John Travolta's official film debut wasn't anything to write home about. He played a hooded cult follower in the low-budget horror flick The Devil's Rain (1975). Only one year, Travolta earned a supporting role as Billy Nolan in 1976's Carrie opposite Sissy Spacek. "I don't think any of us could have known the life the movie would take on for decades...or how many times we'd have to explain to our families the blood was actually corn syrup!" he captioned a throwback Instagram post.
Jim Carrey
Although Jim Carrey made his feature film debut in Finders Keepers, one year later, he earned a leading role in 1985's Once Bitten. Carrey plays a young virgin seduced by a centuries-old vampire looking for fresh blood. The film marked Carrey's first-ever onscreen kiss: "Gosh, my first screen kiss had to be in Once Bitten with Karen Kopins, I believe," he said. "And yeah, it was always a good thing. Always a good thing. I like—I really enjoy other genders. Let’s just say that. Kissing in general is just a good thing."
