They are making another Superman Movie.  Yep, the one released in 2006 with Brandon Routh just didn't cut it, so another movie.  When you do a remake you re-do the entire cast. Henry Cavill was cast as Superman and they just announced who will be playing Martha Kent.

Diane Lane will play Martha Kent in Zack Snyder's

upcoming Superman movie.

Lane will star with Henry Cavill, who was recently announced as the new Clark Kent/Superman. As far as other roles, Kevin Costner is a "person of interest" for the part of Jonathan Kent,

while Viggo Mortensen is on Snyder's radar to play General Zod.
