Deja vu all over again

How ironic....or coincidental that Sigourney Weaver has gotten a chance to repeat (to a degree) the exact same role she played once before:

In Ivan Reitman's 1993 comedy/romance flick "Dave" she played the First Lady to a philandering opportunistic President played by Kevin Kline. Obviously she's developed significantly more ambition since that time, but she sure seems a natural to play the First Lady.

Anyone else notice this?
