Superman Returns
The new movie, directed by Bryan Singer (Usual Suspects, X-Men 1 and 2), will be a sequel to the first two Superman movies. The story wis about Superman leaving Earth for several years and coming back (hence the title) to find things have changed, possibly involving General Zod. Jude Law is rumoured to be up for consideration for that role.
The 3 picture deal Brandon Routh is said to have signed is said to include two Superman movies with the option of the 3rd been a Batman/Superman crossover movie. Christian Bale, the new Batman in Batman Begins, is on the same 3 picture deal.
I haven't seen Brandon act before but Bryan Singer was pretty adamant about casting an unknown (or pretty unknown) actor for the part (it worked with Wolverine) and Brandon Routh is who we got.

This is Brandon Routh dressed up as Clark Kent/Superman for a Halloween party. He does look quite the part, more so than Tom Welling anyway.
Brandon ‘B.J.’ Routh stands at 6’ 2” and celebrated his 25th Birthday on October 9th. Sadly, this is the same day that “our” Superman Christopher Reeve passed away. And Routh was born in Iowa, which is the same state that George Reeves was born, the original silver screen Superman star.
Routh has had some bit parts in television roles on “One Life to Live,” “Gilmore Girls,” “Will & Grace,” and “Cold Case,” and recently wrapped his first film role in an indie titled “Deadly,” starring alongside Laura Prepon, Misha Collins, and Tess Harper.
Brandon is one of the 6 people WB were considering for the character several motnsh ago back when McG was assigned to direct. He even had a screen test but McG reportedly didn't like him. Maybe he didn't like his acting or maybe he just didn't like the overall feel of him but Bryan Singer has obviously seen something in him.
Bryan Singer also, reportedly, thinks that Kevin Spacey would be the perfect Lex Luther but as far as we know, that part hasn't been cast yet.
