Cancelled by CBS in May and resurrected by CBS last month, the drama "Unforgettable" will undergo some not-minor cast changes before it returns to the air next summer.

According to TVLine.com, while Poppy Montgomery, Dylan Walsh and mid-season addition Jane Curtin will all return next season, Michael Gaston, Kevin Rankin and Daya Vaidya will, at the very least, cease to be regulars.

It remains to be seen if those departing regulars will be replaced by a trio of new actors (either cheaper or, if CBS hopes to draw new eyes, bigger names).

But stay tuned.
