Sylvester Stallone to guest star in This is Us

Hollywood actor Sylvester Stallone will soon be seen on the small screen in a guest appearance on the second season of TV show This is Us.

The news was shared by series showrunner Dan Fogelman on Thursday. Stallone will appear in a guest starring role opposite Justin Hartley's character as a co-star in his new film within the series. Fogelman says that Stallone is only currently booked for one episode, but "it's a big part."

Fogelman said Stallone's character talks to Hartley's character about themes that he will relate to in a "beautiful monologue about life." 

Stallone previously appeared with This is Us star Milo Ventimiglia in the 2006 film Rocky Balboa, though it is doubtful if the two will share any screen time in the series due to its multiple timelines. Other guest stars lined up for this season include Dan Lauria and Debra Jo Rupp.
