The Goldbergs

Although the show is largely based on Adam Goldberg's family, the character Erica isn't actually real. The real Goldbergs had three sons: Eric, Barry and Adam; ABC executives told the creators to have one of the siblings to be a girl because the show would be funnier.

The sweaters worn by Beverly (Wendi McClendon-Covey) belonged to the real Beverly Goldberg.

Most, if not all, the posters in Adam's room were posters that the real Adam Goldberg had in his childhood bedroom.
