The 30-year-old "Suicide Squad" actor said he really likes the way "Martian" star thinks of fame, reported People magazine.
"I heard Matt Damon say this one time, and I thought it was so true: 'Your perception of you doesn't change; it's the world's perception of you.
"My perception of me is still the same person, and I still live the same life, he said.
Eastwood said his own choice of a lower-profile lifestyle is more about his natural inclinations.
"I just liked the lifestyle of being outside of the traffic and just being a little slower," he said.
