Christopher Reeve’s 3 kids are celebrating their father in a new documentary. Here’s everything you need to know about them.

The new documentary “Super/Man: The Christopher Reeve Story” chronicles Reeve’s life from beloved movie star to disability advocate alongside Dana, who died of lung cancer two years after Reeve’s death. The doc also gives an unprecedented look inside the Reeve household with rare home videos and interviews with the children.

Here’s everything you need to know about Reeve’s three children.

Matthew Reeve, 44

Born in 1983, Alexandra was the second child Reeve had with Exton.

Instead of going into show business, Alexandra has focused on politics and law. She graduated from Yale and got her law degree from Columbia University.

She began her law career as a litigator at Cravath, Swaine & Moore in New York City. She also taught as an adjunct professor at Columbia for several years.

Alexandra then served as the Senate Judiciary Committee’s chief counsel for IP and antitrust. She was also the founding executive director of the Institute for Technology Law & Policy at Georgetown Law.

She’s currently president and CEO of the Center for Democracy & Technology. Alexandra is married and has a son named Christopher after her father.

Alexandra praises her father for giving her and her siblings a strong work ethic.

“My dad was an incredibly intense person. He did nothing at half effort,” Alexandra said on “Good Morning America.” “And I think all three of us kids have actually inherited a little bit of that. And so that dedication and focus that your work needs to be about more than you, it needs to be about more than yourself and how do you give back to the world that you’re in, that’s shaped each of us today.”

Will Reeve, 32

Will, born June 7, 1992, is Reeve’s youngest child and the only child he had with his wife, Dana.

Will was three years old when his father suffered his injury and only 12 when Reeve died. Less than two years later, when his mother also died, he moved in with a family friend.

Will attended Middlebury College and became a broadcast journalist. He has worked at the MSG Network and was an anchor and correspondent at ESPN.

He currently is an ABC News correspondent, often appearing on “Good Morning America” and “World News Tonight with David Muir.”

In July, Variety reported that Will would make a cameo in James Gunn’s upcoming Superman movie. He will play a TV reporter.

Will told TMZ that though he only had to memorize one line for his cameo, he was still “more nervous” doing that than being on TV for his day job.

“Heroism is so much more than superficial strength and a glossy image,” Will told People about his father’s legacy. “It’s about integrity, showing up for your family, persevering through hard circumstances, and still having that joy for life. That was our dad.”

“Super/Man” is in theaters now.
