The 30 smartest celebrities in Hollywood

Before Matt Damon starred in “Good Will Hunting,” he really hit the books at Harvard.

And before James Franco turned on his wild side in “Freaks and Geeks,” the maths wiz interned at Lockheed Martin.

We rounded up 30 celebrities who are high school valedictorians, Ivy Leaguers, MENSA members, and certified geniuses in their own rights.

These stories of actors, musicians, and TV personalities’ brilliance may surprise you.

Allison Williams is more than the smart one on 'Girls.'

Growing up under Brian Williams' roof, the 'Girls' actress wasn't allowed to act professionally until she graduated from college. She studied English and archaeology at Yale -- taking the kind of classes that make you feel like 'lying on the ground thinking about things,' she says.

When she didn't get a part in Yale's big musical as a freshman, she joined the improv group instead and found she had dad's comedy genes.

Ashton Kutcher hoped to attend MIT or Purdue to study engineering.

But the former 'Punk'd' host lost his scholarships when he broke into his high school as a prank. He ended up at the University of Iowa, but dropped out at 19 to pursue modeling. Kutcher now divides his time between acting and smart investing in companies like Airbnb, Spotify, and Foursquare.

'The sexiest thing in the entire world is being really smart,' Kutcher said at last year's Teen Choice Awards.

Cindy Crawford studied chemical engineering on scholarship at Northwestern University.

Conan O'Brien graduated magna cum laude from Harvard.

Legendary late night host Conan O'Brien was a history and literature major at Harvard University, where the school newspaper dubbed him the 'pre-eminent jokester' of the class of '85. It makes sense, as he was also the president of the Harvard Lampoon, a semi-secret social organisation that published a humour magazine.

His 72-page senior thesis, entitled 'The 'Old Child' in Faulkner and O'Connor,' argued that 'the New South's emerging identity is manifested in the literature of William Faulkner and Flannery O'Connor via the motif of children that age too quickly.'

David Duchovny attended not one, but two Ivy League schools.

The 'X-Files' actor graduated with a B.A. in English literature from Princeton University. He also earned his Master's in English lit from Yale University, but abandoned his Ph.D. studies there when he booked a beer commercial in '87.

During his 'Inside the Actors Studio' interview, Duchovny revealed that the title of his unfinished doctoral thesis was 'Magic and Technology in Contemporary Poetry and Prose.'

Edward Norton worked as an analyst for an entrepreneurial nonprofit.

The two-time Oscar nominated actor studied history at Yale, where a back injury forced his early retirement from the crew team. It was then that he tried his hand at theatre.

After graduation, Norton moved to Osaka to consult on behalf of his grandfather's non-profit, Enterprise Foundation, a leading provider of capital and expertise for affordable housing. There he studied Aikido, a martial art, and became fluent in Japanese.

Emma Watson did Hermoine proud during her studies at Brown.

Flavour Flav co-wrote the first Public Enemy album, heralded for its militant, revolutionary lyrics. Still, he's remembered most for shouting 'Yeahhh boyyyy!' and 'Flavour Flav!' during performances and on a string of VH1 reality shows.

The wall clock-wearing hype man grew up as a musical prodigy, cutting classes to hang out in the band room. He could play about 15 instruments, and learned to play songs by ear.

When Maggie Gyllenhaal returned to her alma mater to accept a personal achievement award, she said her Columbia education taught her to 'acknowledge that I really know nothing.' A thirst for knowledge led her, as a first-year English student, to sneak into the dean's senior seminar.

Little brother Jake Gyllenhaal enrolled when Maggie was a senior, and hoped to major in Eastern religions. Following the success of 'October Sky,' he dropped out after his sophomore year to concentrate on acting.

After a failed run for Ohio governor, he became a broadcast journalist, which Springer called 'the most ethically challenging profession of all time.'

Kate Beckinsale is fluent in four languages.

A young Kate Beckinsale was singled out for her intelligence in grade school; her school reports cited a reading level of an 11-year-old when she was just six.
