William "Bill" Anderson is a character from the 2015 Walt Disney Pictures/Pixar Animation Studio movie and short film Inside Out Series. The Husband of Jill Andersen and the father of Riley Andersen. He is voiced by Kyle MacLachlan.
He used to live in Minnesota. Among others, he served as coach on Riley's hockey team. When Riley was 11, he led his family to move to San Francisco, where he starts work for Brang, a tech startup company. As soon as they arrive, his work consumes him, and he becomes more distant from his family. When at home, he is almost always seen on the phone, discussing investor problems. He is notably absent when Riley's mom brings her to the local league's tryouts. He also becomes somewhat oblivious to Riley's own struggles, and seeing a strange new attitude from her part only results in a fight between them. He tries to make amends later, but his words can't touch her.
He nevertheless remains a loving father, and when Riley admits she misses their old home, he comforts her, and confesses that he misses Minnesota too.
Sometime later, it is seen he has become highly supportive of his daughter at hockey, saying he doesn't want to miss one of her matches, and wearing proudly the team's colors.
