Charlie was heavily referenced in a recent episode of Only Murders in the Building, Hulu's mystery/comedy/drama starring Steve Martin and Martin Short.

Season 4, episode 5 is called "Adaptation." Says BCK's pal Tim:

The opening of this episode features an Asian-American screenwriter talking about his craft. As the scene unfolds, the camera moves in on a picture of Charlie Kaufman, nestled into the corner of a mirror on the screenwriter’s dressing stand. Not once, not twice, but at least three times. And not just a far-away, obscure shot, but directly focused on it.

Ta-da:

Thanks to Tim and u/giga!
