Steven Yeun helped shape his Twilight Zone "A Traveler" episode

Vanity Fair

Yeun received a directed from Jordan Peele and agreed to star in an episode of the CBS All Access drama without knowing anything about his role. “We just kind of openly talked about it, which was really cool,” says Yeun about beefing up his role. “They were so great about letting me have a little input.” Executive producer Simon Kinberg says of soliciting actors' ideas: “We really looked to the actors to bring as much dimensionality and detail and thought to the characters as we and the writers had. And we’ve gotten great work out of actors. Kumail (Nanjiani) is another perfect example . . . He brought a lot to that character. He wrote a lot of the jokes. He was really precise about the transitions the character was going through in the episode . . . It’s that kind of work (that), because it’s one and done, we need from our actors.” ALSO: "A Traveler" called back to another classic Twilight Zone episode.
