Emily Blunt is warming up for Saturday Night Live with a slice of New York City pizza.

At one point in the promo video, it's an overly greasy slice, and another time, it's just a prop. Either way, it's not a large pepperoni split with cast member Beck Bennett.

The Girl on the Train star, who makes her hosting debut on Oct. 15, jokingly confesses that she also played "the train" in the recently-released thriller.

"They had me in a motion-capture suit and all the choo-choo's and the chugga-chugga's are me, she said.

She will be joined by Bruno Mars, who makes his fourth appearance as musical guest ahead of the November release of his third album, 24K.
