Lane cast as Man Of Steel's mum
Diane Lane is set to play Martha Kent in the Superman movie.
The US actress, 46, will star as Superman's adoptive mother opposite British actor Henry Cavill, 27, who has previously been announced as the Man Of Steel.
Director Zack Snyder said: "This was a very important piece of casting for me because Martha Kent is the woman whose values helped shape the man we know as Superman.
"We are thrilled to have Diane in the role because she can convey the wisdom and the wonder of a woman whose son has powers beyond her imagination."
Plot details of the Warner Bros film, which is expected to hit cinemas in December 2012, remain under wraps.
Martha Kent and her husband Jonathan famously adopt the young Clark after he comes from the planet Krypton to earth in a rocket.
Diane's credits include Unfaithful, The Perfect Storm, and most recently Secretariat, opposite John Malkovich.
