In 1991, Margaret Loesch became head of Fox Children's Network. Having championed the "Pryde of the X-Men" pilot in 1989, she was quick to set up an order for 13 episodes of "X-Men". Saban Entertainment was contracted to produce the show and hired a small studio Graz Entertainment to produce the episodes as it did not have sufficient staff at the time to handle production in house. Graz employed the creative staff, wrote and designed each episode, and drew the storyboards. The voice work was done using Canadian studios and South Korean studio AKOM was hired to animate the episodes. "X-Men" was originally to premiere over the Labor Day weekend in September; due to production delays, it was pushed to the end of October. When the animation team AKOM turned in the first episode, it contained hundreds of animation errors, which AKOM refused to fix. Because of time constraints, the episode was aired in an unfinished form. The second episode was turned in just before deadline, with 50 scenes missing and only a single day reserved for editing. The "Night of the Sentinels" two-part episode originally aired as a "sneak preview" on October 31.
