What do the movies 'The Apartment', 'Fade to Black' and 'Pulp Fiction' all have in common?

One similarity that I see is that the director of each also gets a writing credit. There are several films called "Fade to Black" but this holds true for more than one.

"The Apartment" (1960) - Director: Billy Wilder, Writers: Billy Wilder and I.A.L. Diamond

Sorry Spanish, that's not it, not even close. Here's a hint, a VERY good hint...in each film there is someone who looks like a famous person...who's the famous person?

Which "Fade to Black" are you asking about?

Pulp Fiction's famous person was probably working at Jack Rabbit Slim's.

Marilyn Monroe

They are all movies.
