Matt Damon received his first "big paycheck" in Hollywood and decided not to spend it on himself.

In a recent interview with his "Oppenheimer" co-stars, Emily Blunt and Cillian Murphy, Damon revealed he was able to put his mother, Nancy Carlsson-Paige, through her Ph.D. program with the $25,000 he earned for his role in the 1990 drama "Rising Son."

"I bought my brother a car and I put my mom through her Ph.D. program," Damon shared with The Hollywood Reporter. "That was a really cool feeling."

Damon and Blunt recently detailed what it's like to live in the same building in an interview with Fox News Digital.

Blunt, who’s married to John Krasinski and has two daughters with the actor — Hazel, 9, and Violet, 6 — said "it’s the best" having "The Bourne Identity" star under the same roof.

"We do have fun dinner parties. … I love living in the same building," Blunt admitted.
