X-Men 2 scribe Dan Harris told Canadian reporters that Sigourney Weaver was going to be in X-Men 3 as Emma Frost, the White Queen, before director Bryan Singer left to direct Warner Bros.' Superman film.
"We were going to do X-Men 3 for a little while and our big secret or coup was - and it's not going to happen so it's OK - we wanted to have a character that was Emma Frost, a famous X-Men character. She's called the White Queen.
"We were going to ask Sigourney [Weaver] to be it," Harris added. "She was an empath in our version of the movie which means she could control people's emotions."
Weaver said "I try to do that," then joked to Harris, "Write it into Superman."
