I remain confused with the story line, which is plainly put as "Mark Warburg battling Nazi's with King Arthur and the Transformers".
Is that seriously the plot?
I've not enjoyed any of these films since the original but even I'm confused by the teaser trailer I couldn't even tell you what its about just going from that.
As for the Mummy trailer, it does look more like a MI film, a bus sliding across the floor and he sidesteps in through the upper-deck windscreen... I'll be giving this one a miss.
I do however like some of the sound used in the trailer, the plane part before everything happens and the morgue sound have some really unsettling sounds used.
