Pete Davidson's television appearances primarily happen on Saturday Night Live, but he has done guest spots like his upcoming one in The Rookie in other scripted shows before. Davidson was featured on Brooklyn Nine-Nine, The Jim Gaffigan Show, and The Guest Book. As evidenced by his presence in The Suicide Squad, he's also been taking on more film roles, as is often the trend with SNL actors and actresses. Who knows? Perhaps this guest spot on The Rookie will be the role right before he really takes off as an A-lister in Hollywood.
