My wife & I are going to see it on Sat. & I wondered if they showed a Spiderman 3 trailer on IMAX. I've already seen Superman in a normal theater but my wife hasn't and I thought IMAX would be cool. Doesn't it also have some different footage or something?

I did. It was kinda cool. I also had already seen it on a normal screen and didn't think the added 3D was worth the extra $3. There was no Spiderman 3 trailer.

tried to go see it in imax in austin..but it wasn't playing on any of the screens there...that was 2 weekends ago...

I did and was disappointed. The previews weren't good (as mentioned, no Spiderman 3). Only four scenes in 3D, the last of which sucked. They should have also used 3D in the opening credits where the camera is flying through the solar system.

I saw the movie at Edwards off of I-10 in Houston. I also saw Fantasia 2000 there in 3D a few years ago. And it was 3D the entire movie. Without glasses. Much better. Probably because it wasn't live-action, but still.

$11.50 to see Superman in 3D wasn't worth it.

Not worth it in my opinion. See the above post.

Plus, we saw it as a matinee, but at IMAX that's the same price. $7 more than the Cinemark in Grapevine per ticket.
