Speaking in his hometown of Cambridge on Friday, actor Matt Damon addressed graduates at MIT’s commencement ceremony.

In the movie Good Will Hunting, Damon played an MIT janitor who was also a mathematical genius.

In real life, Damon attended Harvard in the 1990s, but dropped out before earning a degree.

On Friday morning, the actor passed along some advice that he once got from former President Bill Clinton.

"You have to engage, and turn toward the problems that you see," Damon said, doing his best Clinton impersonation. 

During his speech, Damon also took jabs at presumptive GOP presidential nominee Donald Trump and ticked off a long list of the world's problems including economic inequality, climate change, extreme poverty, encouraging the graduates to solve them.
