Japanese actor Hiroyuki Sanada, known for his roles in the films “The Wolverine,” “The Last Samurai,” and “47 Ronin,” will be gracing the small screen and taking part in HBO’s sci-fi hit show, “Westworld.”

According to Arama Japan, Sanada’s involvement in the sophomore season of the show has only been confirmed by IMDb, and no other details about his role has been offered.

It seems like “Westworld” Season 2 is really beefing up its cast list. Earlier, Variety reported that “Vikings” star Gustaf Skarsgård, known for his role as Floki in the History series, will be a series regular in “Westworld” together with Fares Fares. Betty Gabriel will also join the cast in a recurring role.

Skarsgård will play Karl Strand, a white-collar guy who is said to be comfortable in the field. Fares, who made appearances in “Tyrant” and “Rogue One,” will play Antoine Costa, a tech expert. Meanwhile, Gabriel will bring to life Maling, a person determined to restore order on the ground.

Before that, “Westworld” cast Katja Herbers from “Manhattan” to play Grace, “a seasoned guest in Westworld whose latest visit comes at the park’s darkest hour,” according to Deadline. Jonathan Tucker and Neil Jackson also landed recurring roles

Many old faces from the show’s first season are also expected to return. Two Season 1 stars — Talulah Riley and Louis Herthum — have been promoted to series regulars for next season. Jimmi Simpson, who played young William, will also be back.

As for Dr. Robert Ford (Anthony Hopkins), show creators Jonathan Nolan and Lisa Joy are keen to bring him back even though he was killed off by Dolores Abernathy (Evan Rachel Wood) during the Season 1 finale.

“I think there will be an opportunity to explore a little bit more of the backstory of how this park came to be, a little more of that story,” Nolan told Digital Spy. “We’ll see the character’s presence will be felt in that sense in terms of filling in a few more of the gaps about the early history of this place.”

The only concern Nolan has right now is how to fit Hopkins into the show, given his busy schedule. “He’s a busy guy, so we’ll see what happens,” he said.
