With "Poker Face" and "Knives Out," writer-director Rian Johnson is a murder mystery connoisseur. His next project will be completely different.

It's no doubt that "Knives Out" director Rian Johnson has a jam-packed schedule — but production on his latest projects, "Knives Out 3" and "Poker Face" Season 2, coincided exactly, creating a conflict that he said was "more stressful" than last time around.

As Poker Face returns with a new batch of even-more-self-contained mysteries for Natasha Lyonne's Charlie Cale to solve, Johnson talks Columbo, the whodunit vs. the “howcatchem,” and how Steven Sondheim influenced the next Knives Out movie.
