By the time Marvel's five-hour announcement about the "Avengers: Doomsday" cast was done, there was a surprisingly long line of empty chairs. But as long as the cast list is, we can't help but notice some huge absences from the roster, including some names we thought were practically mandatory.

Rebecca Romijn, 52, will officially return as Mystique. She starred as the shapeshifter in “X-Men, X2: X-Men United,” “X-Men: The Last Stand” and “X-Men: First Class and Joan in The Punisher.”
