11 Actors Who Look So Much Like Their Parents And Grandparents, They Played Fictional Versions Of Them

In real life, Rubén Jr. went to school with Adam F. Goldberg, whose life the show is based on, though they didn't know each other growing up. So, on the show, Niko Guardado plays a fictionalized version of him. 

In 2018, Adam told the Philadelphia Inquirer, "When I attended Penn Charter, all people would talk about was this legendary dude who made it. Rubén was there the same time as my brother Barry, but my brother was a nerd, so there's no way Ruben would have known him... [On set] we shared a ton of laughs and reminisced about Penn Charter."
