'Barbershop 3' Actor Gets Minor Pay For Majorly Successful Flick

Michael Rainey Jr. might want to start renegotiating a contract for the next 'Barbershop' movie after the HUGE success the third installment just had at the box office.

According to his contract, the teen actor, who plays Jalen in the movie, banked $65k for "Barbershop: The Next Cut" ... which took in more than $20 million.

It's a decent payday for Rainey -- who also has a key role in 50 Cent's TV show, "Power." The bad news is ... he's getting zero back from the movie's success. Then again, he's only 15.

Pray for a role in 'Barbershop 4.'
