Leonardo began his acting career by doing commercials. He landed his first major role as Josh, in Critters 3. After that role, his acting career took off. He's won lots of awards-but he has never won an Oscar.
DiCaprio began producing films after his acting took off. A few movies were the 11th hour and the comedy Gardener of Eden. He can do more than simply acting in movies, he produces them!
Movies produced-Live by Night, The Wolf of Wall Street, Out of the Furnace, and many others.
