Fans of superhero films, rejoice! There's not one, but TWO trailers for 'Man of Steel' attached to screenings of 'The Dark Knight Rises.' So what does this mean for you?

If you're heading to the theater to see 'The Dark Knight Rises' this weekend, you'll be pleased to know that there's two different trailers for the Christopher Nolan-produced, Zack Snyder-directed Superman flick 'Man of Steel.'

The film stars Henry Cavill as Clark Kent/Superman in Snyder's telling of his origin story, and how he comes to accept and use his powers to protect his new home on Earth.

According to Slashfilm, the first trailer has a voice over by Clark Kent's adopted dad (Kevin Costner) and the other has a voice over by his legit father, Jor-El (Russell Crowe).  Superman Homepage has descriptions of both trailers and while the video is the same, where it differs are two different voiceovers.

Costner's voice over:

You’re not just anyone. One day you’re gonna have to make a choice. You have to decide what kind of man you want to grow up to be. Whoever that man is, good character or bad, it’s going to change the world.

And Crowe's voice over:

You will give the people an ideal to strive towards. They will race behind you, they will stumble, they will fall. But in time, they will join you in the sun. In time you will help them accomplish wonders.

There's no rhyme or reason to which trailer you'll see when and where but hopefully both will show up online sooner rather than later.
