Who are the biggest movie stars under age 40?

I just realized the stars of the 90s and 2000s are pushing 60, 70, 80 years old. Who are the young superstars in movies today?

Jeez, I was going to say Bradley Cooper and Dwayne Johnson, but they are 44 and 46 respectively. Emily Blunt is 35, Jennifer Lawrence is 28. Chris Hemsworth (Thor) is 35.

Jennifer Lawerence has been pretty successful so far with several highly acclaimed roles- Chris Hemsworth has made MILLIONS playing Thor and with Endgame, he is contractually done with Marvel--------which means if they want to do another THOR movie with him........they will essentially have to give him a blank check, and tell him to fill in the zero's.-
