Sylvester Stallone to Join 'This Is Us' Cast

This Is Us creator Dan Fogelman is aware that viewers of his breakout time-jumping family drama want to know how Jack (Milo Ventimiglia) died — and season two will provide those answers.

"If that is a question that has haunted people, over the course of the second season, they will get all the answers they want," Fogelman told reporters Thursday at the Television Critics Association's summer press tour. "The first episode has a big giant piece of the puzzle that will potentially set the internet abuzz and hopefully give some momentum toward that storyline."

As part of Kevin's storyline, Sylvester Stallone will guest-star as his co-lead in the movie he's working on.

"We needed his big co-star, and Sly Stallone is coming to do a huge part on the show as Kevin's co-star and father figure in the film he's shooting," Fogelman said.
