He stood up for his colleagues.
Lisa Jakub was a teenager when she played the role of Robin Williams’s daughter in Mrs. Doubtfire. Because of the filming process, Lisa’s teachers at school would have to give her an increased workload, and they weren’t happy about it. That’s why she was kicked out. Lisa was upset about it, and Robin Williams noticed this.
When she told him what happened, he wrote a letter to the school asking them to allow her to return to her classes and explaining that she was just trying to pursue a career, while also getting her education. He also said kind words about her character and her work. Unfortunately, the letter didn’t work, but the school framed it and hung it in the principal’s office.
yea and look where that idea is today
