While filling in for Kimmel this week, the actor-director got the attention of Laura Ingraham, who said she’d never seen the show before.

On Thursday, for his final round, Luna brought it home by opening the show with mariachi music, giving Kimmel co-host Guillermo an executive producer promotion ("I don't know if I can do that, but I just did,"), and delivering a final must-watch monologue appealing to the audience for unity, not division.

On Monday night, award-winning actor-director Diego Luna became the first Mexican to host a late-night talk show in English. Filling in for the titular “Jimmy Kimmel Live!” host, who was out on vacation, Luna took over as the special guest host of the late-night comedy show and seized the opportunity to speak up for L.A.’s immigrant community.
