The Sopranos

When Jamie-Lynn Sigler was first called in to audition for Meadow Soprano, she knew nothing about the premise of the show. From the title, she thought it might be about opera singers.

Tony Sirico only agreed to sign on for the show if it was guaranteed that his character Paulie "Walnuts" Gualtieri would not be a "rat", an informant. As Sirico explained in James Toback's documentary The Big Bang (1989), he had served time in prison for robbery. Altogether, Sirico's rap sheet included at least 28 arrests. Reportedly, he also appeared briefly in an uncredited role in 'The Godfather: Part II' (1974).

To settle salary disputes after Season Four, James Gandolfini gave each cast member $33,333 from his own pocket.
