James Franco’s former high school has taken down a mural he painted and plans to remove other art donated by the celebrity alumnus who is facing allegations of sexual misconduct in Hollywood.Removing the artwork from Palo Alto High School is “in the best interests of our students in light of our educational mission,” Superintendent Karen Hendricks said Thursday in a statement.The statement did not mention the scandal surrounding Franco, which the school’s newspaper reported was the reason the artwork was removed.
