The producers of “Lost” convinced ABC that the 2-hour season finale really needs to be 3 hours long. They also insisted that the final 2 hours HAD to air back-to-back. Because of this, ABC had to re-do their may schedule and decided to give us an extra hour of “Grey’s.” The schedule looks like this:

May 15
8 pm: Ugly Betty
9 pm: Grey’s Anatomy
10 pm: Lost (part 1 finale)

May 22
8 pm: Ugly Betty finale
9-11 pm: Two-hour Grey’s Anatomy finale

May 29
8 pm: Lost encore (part 1 finale)
9-11 pm: Two-hour Lost finale
