For those outside of the entertainment industry, a rider lists out an artist’s specific personal and technical needs for hosting them for an event- anything from bottled water and their green room to sound and lighting requirements. You can learn a lot about a person from their rider. This is where rocks bands list their requirement for green M&Ms (which is actually a surprisingly smart thing to do). This is also where a famous environmentalist requires a large gas-guzzling private jet to fly to the event city, but then requires an electric or hybrid car to take said environmentalist to the event venue when in view of the public.
When I got Robin Williams’ rider, I was very surprised by what I found. He actually had a requirement that for every single event or film he did, the company hiring him also had to hire a certain number of homeless people and put them to work. I never watched a Robin Williams movie the same way after that. I’m sure that on his own time and with his own money, he was working with these people in need, but he’d also decided to use his clout as an entertainer to make sure that production companies and event planners also learned the value of giving people a chance to work their way back.
God rest the man's troubled soul.
