'This Is Us': Sylvester Stallone Will Guest Star in Season 2

The cast of This Is Us teamed up for the 2017 Summer TCA Press Tour!

Milo Ventimiglia, Chris Sullivan, Mandy Moore, and Susan Kelechi Watson spoke on stage during the NBCUniversal portion of the event on Thursday (August 3) at the Beverly Hilton Hotel in Beverly Hills, Calif.

They were joined by their co-stars Ron Cephas Jones, Sterling K. Brown, Chrissy Metz, Justin Hartley, and creator Dan Fogelman.

The group dropped lots of season 2 teasers, including the revelation that Sylvester Stallone will appear in a plot line about Kevin’s big movie! The movie will feature Kevin as a young soldier and will be directed by Ron Howard in the show, according to Deadline.

Dan said that Milo helped enlist Sylvester, as he starred with him in 2006′s Rocky Balboa. “We needed a big star for his [Kevin's] movie,” Dan revealed, “and we’re really excited about the [episode] script.”

When asked about Jack’s death, Dan explained, “If I say everything, there is nothing to watch. If this is the question that is haunting people, in the course of the second season, you’ll get the answers and more. The first episode has a first giant piece of the puzzle that will set the Internet abuzz. That’s the best I can say without spoiling.”

FYI: Mandy is wearing Roksanda with Malone Souliers heels.
