As authorities continue what could be a months-long investigation into the on-set tragedy that killed cinematographer Halyna Hutchins, those on the business side of things in Hollywood are wondering why Alec Baldwin was involved with “Rust” in the first place. Earlier this year, the actor and producer told The Hollywood Reporter, “I have six kids, I don’t want to work anymore.” Working for a short time on a $6 million movie like “Rust” may be a great deal for Baldwin, but after his pay day, it’s possible not much money was left for the crew, which led to cutting corners and ultimately, a deadly accident.
