20. Sean Penn
Sean Penn had a positive impact on the project right from the beginning. The actor is said to have attended Santa Monica High School, where he shared a class with Robert Downey Jr., Charlie Sheen, and Rob Lowe. Outside of school, they were also good friends of each other.
Charlie Sheen was fired because of his relationship with Robert Downey Jr. Only Sean had been in Rob Lowe’s high school class. It’s incredible to think that all four of their closest friends ended up in the entertainment industry. We have no idea what is going to take place.
