Jack L.

The nervous fellow played by Alfred Molina in this mini-series is almost entirely a fiction, and a demeaning one.
The scene at the William Morris Agency, Lange's outfit and dialogue references an infamous scene from the 1981 Joan Crawford biopic Mommie Dearest, right down to the use of the F-word.
