Marvel actor Simu Liu on his rise to fame as an immigrant and his new memoir: "I'm going to be unapologetic"

Simu Liu, who became the first Asian superhero in a Marvel film, says he's still struggling to process his success. In his new memoir, "We Were Dreamers," the actor details his rise to fame as an immigrant child, explaining how his family life was far from ordinary and often tumultuous.

"I'm going to be unapologetic about who I am and where I come from," Liu told CBS News correspondent Nancy Chen. "I'm going to be a representative."

Liu spent his early years in China and was left in the care of his grandparents after his parents emigrated to Canada for graduate school. At the age of around four and a half, Liu says his father returned to China to move him to Canada as well.
