 Matsumoto threatened to revoke his approval of this OAV when he  discovered that one of the enemy ships was to be shaped like a  Jewish Star of David. Matsumoto, who is against racial intolerance,  couldnt condone a religious symbol being used as a villains ship  and demanded that the design be changed or he would derail the  production. The matter was resolved amiably, and the ships design  was completely overhauled.
