If 21-year-old actor Timothée Chalamet isn't on your radar yet, just you wait, because you can bet he will be when awards season rolls around. The star's recent popularity is due in large part to his exemplary roles in the recent hits Call Me by Your Name and Lady Bird. (Just Google his name and you'll find years-worth of rave reviews .) The other half of the hype is all thanks to his fluffy head of hair.
