TV series.

Busan Film Critics Awards. He also starred in
Ha Ha Ha, which won the top prize in the
Un Certain Regard section of the
2010 Cannes Film Festival, at which Yoo and his fellow cast members walked the red carpet. When asked to describe the actor, Hong said that "Yoo is... a kind person." [...] I just... like him. I like him a lot. He is someone with a drive that doesn't irritate me. His honesty doesn't irritate me either and I like his energy. His energy has a clean color. And I think he's a lot of help when we work together." The director cast him opposite renowned French actress
Isabelle Huppert in Hong's first English-language film
In Another Country. He described Huppert as "a real joy" to work with, while she praised him as "kind and charismatic." After a five-year absence from television, he returned in the series
My Husband Got a Family (also known as
Unexpected You) co-starring
Kim Nam-joo. The drama was a big hit, it not only consistently topped its timeslot throughout its long run, but ranked number one on the 2012 yearly TV ratings chart. As a result, Yoo enjoyed his biggest surge of mainstream popularity since his debut, landing commercial contracts and gaining the nickname "Nation's son-in-law". In 2012, he published his memoir titled
The Invention of Happiness. Yoo said he began writing diaries back in university when his professor recommended that he try filling up at least one journal each year with personal reflections. The book contained highlights from his 20 years of journaling life—from his days as a college student, moments on the set of several productions to his travels and vacations—as well as poems and sketches made by the actor in his everyday life. He donated all of the proceeds from the book to charity, especially to impoverished children. For the aerial action blockbuster
R2B: Return to Base, Yoo along with the rest of the cast had to undergo months-long physical training for their role as jet fighter pilots. The actors also had to pass mandatory tests for actual pilots to be able to get into the cockpit—in a low-pressure chamber, emergency escape routine, simulated flight as well as training to develop tolerance for acceleration. Yoo reportedly passed out twice before he passed his 6G test, only passing on his third attempt. Yoo underwent knee surgery after an injury to his
cruciate ligament while filming
Fists of Legend. The action movie revolved around a group of middle-aged men who fight on a reality show for a cash prize. On December 19, 2013, he released his first album, titled
Junes; besides singing, Yoo composed, wrote the lyrics and produced all the seven songs included. Yoo's second album,
