Here is Alec Baldwin as Blake in the movie Glengarry Glen Ross. Written originally by David Mamet as a play, it debuted in London in 1983 and then shown later the same year in NY and Chicago. In 1992 it was adapted for film.
Baldwin almost didn’t play this part: He left the project after signing on due to a contract dispute. He reconsidered knowing the script was one of the best he’d ever read.
